Question

Sandy is a cat breeder who bred her prize silver male cat "Davy" to a non-silver female "Ruthie" homozygous recessive for the allele i at the intense silver locus. Cats are silver if they have one I allele. Davy and Ruthie had 3 kittens: Stevie; Larry and JacquiO. Sandy let Larry and JacquiO have offspring together and they produced 2 male cats Jim, a non-silver cat homozygous for the recessive i allele, and "Charlie" a silver cat. Sandy crossed Charlie to "Zarah" a pure-breeding silver cat from another breeder. If Charlie is a pure breeding silver cat complete the sentence describing his ancestry. Charlie has ____ genotype and is the product of _______ ; his mother ___ had the genotype __, and his father ____ had the genotype ____.

II; a consanguineous union; JacquiO Ii; Larry Ii

ii; a consanguineous union; JacquiO II ; Larry ii

Ii; a mating between unrelated cats; JacquiO Ii ; Larry Ii

II; a mating between unrelated cats; JacquiO Ii ; Larry II

ii; a consanguineous union; JacquiO II ; Larry ii

Ii; a mating between unrelated cats; JacquiO Ii ; Larry Ii

II; a mating between unrelated cats; JacquiO Ii ; Larry II

Ii; a consanguineous union; Ruthie ii ; Davy II

Explanation / Answer

d. II; a mating between unrelated cats; JacquiO Ii ; Larry II

As zarah was not in their family so it is the union between the unrelated cat. Charlie was homozygous for dominant allele I. His mother was JacquiO Ii with heterozygous dominant allele and father was Larry with homozygous dominant allele I.
