In a group of cows, some individuals have solid coloring and other have white spots. In this group, the gene for coat pattern trait has two alleles. The allele for white spots (a) is recessive to the allele for solid coloring (A). What is the expected ratio of homozygous recessive to homozygous dominant offspring genotypes? Choose the most likely ratio. 1:2, 1:1, or 2:1
