Question

Calico cats are almost always female because the gene for coat color is

carried on the X chromosome. The Y chromosome in cats has no color
gene. Explain how a calico cat might be a male. *

Answer 1

Answer:In rare cases, a male cat can inherit two X chromosomes in addition to his Y chromosome (Klinefelter Syndrome). ... If the two X chromosomes do not carry the same allele (i.e., the cat's genotype is XBXbY), then the male will express calico coloration, just as a female would.
