When a gene possesses both dominant and recessive. We used PCR-RFLP diagnostics to genotype cats in our colony for the published alleles. The Siameseallele cs at the albinogene causes temperature-sensitive pigment expression.

Thomas Hunt Morgan Mald Gender Female Genetic Disorder Trait Achondroplasia Cystic Fibrosis Huntingtons. Cats with Ccs genotype will be full-colored and are carriers of Siamese colorpoint restriction. Domestic Cat Breeds.

A Seal Sepia can be created by the following mates. Kittens born with intermediate coloring are born with blue eyes but change over time. Burmese is an allelic variant that is less temperature-sensitive producing more pigment.

However at the tips of the extremities which are much cooler the enzyme is.
