Parent genotypes: rr x Rr
● The phenotypic ratio would be 1 short hair: 1 long hair.
● To determine the probability of offspring having short, black hair, we need to consider both the genotype and the phenotype. The male parent has a genotype of rr, which means it can only pass on the recessive allele for hair color (black). The female parent has a genotype of Rr, which means it can pass on either the dominant allele (black) or the recessive allele (white). Since black hair is dominant, there is a 100% probability that the offspring will have black hair.
● To determine the probability of offspring having long, white hair, we need to consider the genotype and phenotype of the female parent. The female parent has a 50% chance of passing on the recessive allele for hair length (long), and a 50% chance of passing on the dominant allele (short). Since white hair is recessive, there is a 50% probability that the offspring will have long, white hair.
A male rabbit that is homozygous recessive for hair and color is crossed with heterozygous female
rabbit.
