When mating a chinchilla rabbit with a grey rabbit, what is the predicted outcome if grey is recessive?

When mating a chinchilla rabbit with a grey rabbit, what is the predicted outcome if grey is recessive?

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

Answer: (A)

To understand the predicted outcome of mating a chinchilla rabbit with a grey rabbit, considering that grey is a recessive trait, we first need to establish the genetic basis for these traits. In this scenario, let's denote the chinchilla fur color as a dominant trait (represented by "C") and the grey fur color as its recessive counterpart (represented by "c"). A chinchilla rabbit would have at least one "C" allele, while a grey rabbit would possess two recessive "c" alleles (cc). When we breed a chinchilla rabbit (potential genotypes CC or Cc) with a grey rabbit (cc), we must consider both potential genotypes for the chinchilla rabbit: 1. If the chinchilla rabbit is homozygous dominant (CC), then all offspring would inherit one "C" allele from the chinchilla parent and one "c" allele from the grey parent. Consequently, all offspring would display the chinchilla phenotype (C carrying the chinchilla trait) and none would exhibit grey fur. 2. If the chinchilla rabbit is heterozygous (Cc), half of the offspring would inherit the "C" allele, resulting in chinchilla
