In cаts, the brоwning gene cоdes fоr аn enzyme involved in pigment production. The B аllele is dominant and leads to black colored fur and the recessive b allele leads to a chocolated colored fur. A cat breeder crosses two black cats and gets a litter of cats where 6 kittens are black and 3 are chocolate. What is the genotype of the two parental cats (P generation )? If you were to randomly select a black F1 kitten from the litter in the previous question, what is the probability that the kitten would be homozygous for the B allele? The breeder wants to perform a test cross to determine the genotype of one of the black F1 kittens. Once this kitten is old enough to be crossed, it will be crossed to another cat with what genotype?
