When mating a chinchilla rabbit with a grey rabbit, if grey is recessive, what is one expected outcome?

When mating a chinchilla rabbit with a grey rabbit, if grey is recessive, what is one expected outcome?

• A. 50% grey, 25% chinchilla, 25% albino
• B. 75% grey, 25% chinchilla
• C. 25% chinchilla, 50% grey, 25% full color
• D. 100% grey

Answer: (A)

To understand the outcome of mating a chinchilla rabbit with a grey rabbit when grey is a recessive trait, we need to apply the principles of Mendelian genetics. First, let's define the genotypes. Since grey is recessive, its genotype would be represented as 'gg,' while the chinchilla rabbit, which is typically a phenotype resulting from a different allele, could be represented as 'Gg' (where G indicates the chinchilla trait and g is the allele for grey). When we cross these two rabbits—assuming one is heterozygous for the chinchilla trait (Gg) and the other is homozygous recessive for grey (gg)—we can set up a Punnett square to visualize the possible offspring. The combinations of alleles from the chinchilla and grey rabbits would yield the following genotypes in the offspring: 'Gg' (chin-chinchilla) and 'gg' (grey). In this case, the expected offspring ratios would be: - 50% Gg (chinchilla) - 50% gg (grey) This accounts for the potential outcomes of the genetic cross. The chinchilla phenotype would express as one of the possible outcomes, and grey

This accounts for the potential outcomes of the genetic cross. The chinchilla phenotype would express as one of the possible outcomes, and grey
