The expected coat colors by sex of their offspring would be as follows: 1 orange female: The orange allele from the male is passed on to a female offspring. 1 tortoiseshell female: The tortoiseshell coat color comes from the X-inactivation process in heterozygote females.
Just like with eye colour in humans, coat colour in cats has a polygenic inheritance pattern meaning there are more genes involved in determining coat colour.

As weve discussed before, coat color has no correlation with temperament (just like eye color in people), and we do not breed yellow to chocolates, as you will dilute the dark pigmentation that we desire around the eyes and nose, and the color of the chocolate coat.

Sheltie Coat Color Inheritance. Sheltie (Shetland Sheepdog) puppies look like their parents, but not exactly.See: an explanation of Sheltie coat color inheritance for the genes in this calculator.

Coat color inheritance is complex and can vary by breed. For precise results, consult a geneticist or use DNA testing.Process: The calculator applies Mendelian genetics and dominant/recessive inheritance rules. Output: A list of potential coat colors and probabilities for the puppies.
11.3b X-linked inheritance of white eyes in Drosophila:The F1 flies are interbred to produce the F2s.Also horns in sheep, coat color in Ayrshire cattle etc. Famous example of a sex-linked trait: hemophilia.
black - recessive black. Color inheritance by gene linkage. One theory of alpaca coat color inheritance stands apart from all the others.
