1985 PPGSa A breeding colony of Elaphe guttata guttata and hybrids between E. g. guttata and E. g. emoryi deriving from more than 200 original individuals has been developed during a period of 20 years. Five amelanistic E. g. guttata from the original Bechtel-Groves Baltimore stock and four wild-captive anerythristic E. g. guttata have been outbred to the offspring of more than 200 wild - captive E. g. guttata or E. g. emoryi which were orginally selected for desirable colors and patterns. Selective breeding for mutant coat color genes (Inventory 1984) and natural color and pattern variations without inbreeding. An effort has been made to avoid matings of individuals sharing as much as a single grandparent. Individuals indentities and records have been maintained so that full pedigrees back to the original wild or Baltimore stock are used in determination of matings. Individuals are housed separately and desired matings are accomplished after the female develops ovarian follicles. Several families of each type are maintained so that outbred offspring exhibiting the extremes of the various characteristics can be produced. Animals bred through as many as eight captive generations represent hybrids between individuals from the entire ranges of E. g. guttata and E. g. emoryi. Hybridization of subspecies, species, and genera in the family Colubridae is being done. This work is based on the hypothesis that species within the family have, with a few exceptions, been essentially stable since before separation of the continents. Most of the same chromosome number (36). If there has not been a transposition of important genetic information between chromosomes during the period following speciation, then hybrids may be fertile. E. g. guttata x Pituophis m. annectens hybrids have shown to be fertile. Copulations induced between species or genera occupying the same geographic area were frequently of brief duration (5 to 10 seconds only), caused extensive oviduct bleeding and, resulted in no offspring. Copulations between differnt genera from distant geographic areas were frequently successful. The physical isolation mechanisims designed to prevent hybridization of species occupying the same geographical areas: oviduct and penis size and shape; may be less operative when animals derive from different geographic areas. Duration of copulation was determined by the female. The normal copulation period for E. g. guttata is 30 minutes. The normal copulation period for Lampropeltis getulus is 60 minutes or more. When L. g. getulus males mated with E. g. guttata females copulation was terminated after 30 minutes. When E. guttata males copulated with L. getulus females, copulation continued for 60 minutes or more. Aparently a neurological stimulus is required for ovulation and when the female has received the required stimulus she signals the male and copulation is terminated. E. guttata males exhibited aversion to the keeled scales of Pituophis. Outbred males nevertheless frequently achieved copulation.

Female corn laid 25 good eggs of which 21 hatched. 3 eggs noted to be 30% larger than normal corn snake eggs but much smaller than normal gopher snake eggs. Of these, two intergrades and one stillborn hatched after 65 days. (pure corn eggs = 60 days, gophers = 70 - 75 days). Babies appear healthy and are growing well after six months.

Hybrid Or Intergrade
1986 PPGSa Bred during 1986. E. guttata X Pituophis melanoleucus hybrids nearly equally resemble both parental genera in their body form, coloration and behavior. Elaphe guttata X Lampropeltis getulus californiae hybrids much more closely resemble their Lampropeltis parent. Dominant alleles are usually those that have been in the gene pool for the greatest time period. The dominance of Lampropeltis characteristics over those of Elaphe, therefore, may indicate that Lampropeltis represent an original or ancestral form from which genera such as Elaphe or Pituophis evolved.
