Question
A farmer is interested in a new colour pattern in his breed of cattle. This trait is controlled by a single autosomal gene (Gene R) with two alleles. The R-allele results in a spotted colour pattern, while the recessive allele causes a solid colour. The farmer has a cow that has the spotted pattern. Can you suggest how the farmer can determine the genotype (RR or Rr) of his cow in a single cross? Describe this cross and provide details on how you would interpret the results.
Expert Solution
