Coat color in cats is determined by genes at several different loci. At one locus on the X chromosome, one allele (X +) encodes black fur; another allele (Xo) encodes orange fur. Females can be black (X +X +), orange (XoXo), or a mixture of orange and black called tortoiseshell (X +Xo). Males are either black (X +Y) or orange (XoY). Bill has a female tortoiseshell cat named Patches. One night Patches escapes from Bill’s house, spends the night out, and mates with a stray male. Patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. Give the genotypes of Patches, her kittens, and the stray male with which Patches mated.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
