In the first cross, a rabbit with the chinchilla coat colour is mated to a rabbit with a Himalayan coat colour that is known to be homozygous for this trait. Calculate the theoretical probability of this cross producing each of the following phenotypes shown below. Record your answer as a full percentage for each phenotype in the order shown below. Match the phenotype with percentage. Percentages can be used multiple times. v V Light Grey Full Colour Himalayan Chinchilla 1. O 2. 25 3. 50 4. 75

Question
Use this information to answer the next two questions.
Multiple alleles control the coat colour of rabbits.
● The dominant allele, C, produces grey colour.
The Coh allele produces silver grey (chinchilla) colour when homozygous.
The Challele is recessive to both the full colour allele and the chinchilla allele.
●
●
The Challele produces a white colour with black extremities (Himalyan)
The Ca allele is recessive to all other alleles, and produces no pigment (albino).
The dominance hierarchy is C> Cch > Ch > Ca.
The table below provides the possible genotypes and phenotypes for coat colour in rabbits. Notice
that four genotypes are possible for full-colour but only one for albino.
