Polygenic Inheritance: Cat Coat Color
Read aboutthe inheritance of cat coat color In each cat below, predict the phenotype of each genotype and color
in each catl Make sure you indicate whether each cat is male or female
One gene that affects coat color in
cats is an x linked gene we'll call the
pigment gene. One allele causes black
fur (X) and one allele gives the cat
orange fur (X"). These alleles act in a
codominant manner, because when a cat
has two different alleles (XB Xb), the cat
has a pattern called tortoise shell, where
the cat has both orange and black hairs.
The Y chromosome does not have this
coat color gene
There is another gene that affects coat
color in cats called the piebalding gene.
This gene is on an autosomal
chromosome and the alleles affect the
amount of white patches that appear in
the cat's coat, Some cats (ss) have o
white patches and their other colors are
blended, not patchy. Some cats (SS or
Ss) have white patches and their other
colors are…
