Key Takeaways on What The Process Takes

  • Corn snake breeding involves understanding the genetics and morphs of these reptiles, which determine their unique colors and patterns.
  • The breeding process requires careful preparation, including selecting healthy snakes and properly preparing them for brumation or hibernation.
  • Incubating and caring for the eggs is crucial, with factors such as temperaturehumidity, and monitoring plays a vital role in successful hatchings.

Understanding Corn Snake Genetics and Morphs For Breeders

Corn snakes are reptiles that come in various colors and patterns, known as morphs, which are determined by their genetics. The genetics are a mix of female and male corn snakes.

What is a Corn Snake?

A Corn Snake, scientifically known as Pantherophis guttatus, is a popular pet snake native to North America. These snakes are often brightly colored with patches resembling corn kernels, hence their name.

They’re non-venomous and typically friendly, which makes them an ideal choice for reptile enthusiasts. The breeding cycle of a Corn Snake involves specific steps from brumation to successful hatching of eggs which usually occurs 30-45 days post-mating.

How do Corn Snake morphs work?

Corn Snake morphs are a fascinating aspect of their genetics. These unique patterns and colors result from the combination of genes inherited from parent snakes during breeding.

Each Corn Snake carries two sets of genes, one from each parent, contributing to its physical characteristics like color and pattern.

Understanding these variations requires knowledge of heterozygous and homozygous snake genes. Heterozygous means the snake has two different forms (or alleles) for a particular trait, while homozygous implies identical alleles.

Traits such as skin color or pattern can be dominant, co-dominant, or recessive depending on how they appear in offspring when paired with other traits.

The Snow Corn Snake is an excellent example of this concept – it’s a double recessive morph that combines Amelanistic and Anerythristic traits. Both parents must carry these specific genes to produce this mesmerizing white-colored variety with pinkish-red eyes! Another important point is that not all baby corn snakes will be Snow Corn Snakes even if both parents are; some may carry the genetic potential or “traits” without visually expressing them.

Heterozygous vs. homozygous snake genes

Snakes, like corn snakes, can have either heterozygous or homozygous genes. A snake is considered heterozygous if it possesses two different forms of a gene from each parent. This variety often leads to more diversity in potential offspring’s appearance and traits.

On the contrary, a snake with homozygous genes will have identical forms of a certain gene from both parents. In such cases, these particular genes are definite to appear in their progeny, making them key players when breeders aim for specific traits or morphs.

Understanding this basic genetic concept plays an integral role in the breeding process as it greatly influences the expected outcome of each breeding pair.

Dominant, co-dominant, or recessive genes

Corn snakes exhibit various genetic traits, categorized as dominant, co-dominant, or recessive. Dominant genes are expressed in the snake’s physical appearance when present.

For example, if a corn snake has a dominant gene for red coloration, it will have red scales.

Co-dominant genes work slightly differently. When both copies of a co-dominant gene are present in a snake’s DNA, they interact to create a unique trait or pattern. An example is the “amelanistic” morph in corn snakes, where both copies of the amelanism gene result in reduced pigmentation and brighter colors.

Recessive genes only show their effects when two copies are inherited from each parent. These genes often produce more subtle variations in patterns or colors than dominants and co-dominants.

Some examples include hypomelanism and anerythristic morphs.

Materials needed for breeding

To successfully breed corn snakes, you will need a few essential materials. First and foremost, you will need a suitable enclosure for the breeding pair of snakes. This should be large enough to accommodate both snakes comfortably and provide them with adequate space to move around. Note this should be the only time two snakes are kept together as they are solitary reptiles.

You will also need a nesting box or hideout filled with damp sphagnum moss where the female can lay her eggs.

Maintaining the right temperature and humidity levels is crucial for successful breeding. You will need a reliable heat source, such as heat pads or lamps, to keep the enclosure warm.

Additionally, it’s important to have a thermometer and hygrometer to monitor these conditions accurately.

Another essential item is an incubator for hatching the eggs. This will ensure that the eggs receive optimal conditions for development. Choose an incubator that allows you to control temperature and humidity levels effectively.

Selecting the right snakes you want to breed

Choosing the right snakes you intend to breed is crucial in corn snake breeding. Selecting healthy and genetically diverse snakes is important to ensure successful breeding and produce high-quality offspring.

Look for adult snakes with good overall health, with no signs of illness or disease. Consider their genetics, aiming to pair individuals with different morphs to create unique combinations in their offspring.

By carefully selecting your breeding pair, you increase the chances of producing healthy and visually appealing baby snakes.

Preparing Corn Snakes for brumation and hibernation

Before you begin breeding corn snakes, preparing them for brumation or hibernation is important. Here are the steps to follow:

  1. Gradually reduce feeding: Start reducing the frequency of feeding your corn snakes about 4-6 weeks before the intended brumation period.
  2. Lower temperature and lighting: Decrease the temperature in their enclosure by a few degrees each week until it reaches around 50-55 degrees Fahrenheit. Also, reduce the amount of light they receive each day.
  3. Adjust humidity levels: Maintain a humidity level of around 50-60% during this time to keep your snakes comfortable.
  4. Limit handling: Minimize handling during this period as it may disrupt their natural cycles.
  5. Observe behavior changes: Adult corn snakes become less active during brumation and may hide more than usual. This is normal.
  6. Provide a suitable hiding spot: Make sure your snakes have a cozy hiding place where they can feel secure during brumation.
  7. Monitor health regularly: Monitor their weight and overall health throughout the process to ensure they are doing well.

Brumation is a natural process, and snakes will do this to save energy and get through the worst of the colder weather in the wild. It’s also the rest period before mating. When your snakes out of brumation in mating season, you might see signs of breeding readiness. Keep reading to know the signs to watch for.

Observing signs of breeding readiness

When a female corn snake is ready, she will exhibit clear physical and behavioral signs when they are ready to breed. One of the most obvious signs is a swelling in the lower third of their bodies, indicating that they have developed eggs-filled follicles.

Another sign to look for is increased activity and movement, as well as scent marking their environment with pheromones to attract potential mates. Female corn snakes may also begin shedding their skin more frequently in preparation for mating.

It’s important to closely observe these signs to ensure you can pair your snakes at the right time for successful breeding.

Introduction and Courtship

As the male detects the female’s scent, he will approach her, initiating the courtship by rubbing his chin along the length of her body, particularly focusing on her back and tail. This tactile stimulation is a crucial part of the courtship ritual. If the female is receptive to his advances, she will raise and arch her tail, signaling her willingness to mate.

The male will then line up their bodies, allowing their cloacal vents to come into contact. This cloacal alignment is essential for transferring sperm from the male to the female. The mating process can be prolonged, with the snakes remaining intertwined for several hours when snakes mate.

This must happen for them to breed successfully. When you breed your snakes and know it was successful, the two corn snakes should be separated, and the male should be removed from the enclosure. It would be best if you did not leave the snakes together.

Post-Mating and Egg Laying:


After successful mating, the female corn snake will undergo noticeable behavioral and physical changes. She may become less active and exhibit a significant increase in girth as the eggs develop inside her.

Her appetite might also diminish during this gravid period.  Around six weeks after mating, usually around 45 days after mating, the female will search for a suitable spot within the enclosure. This location is typically a secluded, moist area that offers the right conditions for incubating her eggs.

Once she finds the perfect spot, she will lay her clutch of eggs; the average number of eggs per clutch is 12, elongated and covered in a soft, leathery shell. Once the female has laid her eggs, she may coil around her eggs briefly, providing a semblance of protection; corn snakes do not exhibit maternal care.

After laying, she will leave the eggs to incubate, The female can then be returned to her normal enclosure, and the eggs can be transferred to an incubator. They will hatch in about two months, depending on the temperature and humidity of the environment.

Read on, for everything you need to know about incubating and caring for the eggs.
