Which of these Punnett squares represents a cross between a homozygous dominant parent and a heterozygous parent?
- 12. Multiple Choice
In a certain breed of cats, having black hair is the result of two dominant alleles for hair color (HH). The heterozygous genotype (Hh) produces a cat that has black and white spots. Having two recessive (hh) genes results in a white-haired cat. In the Punnett square below, what are the phenotypes of the parent cats?
2 spotted cats
2 black cats
1 spotted cat and 1 white cat
1 black cat and 1 spotted cat
