A farmer purchased and planted F1 hybrid seed in 2022, resulting in a high-yielding and uniform crop. Pleased with the results, the farmer collected F2 seed from crossing the F1 plants (F1 x F1 cross) and planted this F2 seed in 2023. Based on our understanding of genetics, what outcome would we expect in terms of crop uniformity and yield in the F2 crop?

If a cross produced a 12:3:1 phenotypic ratio in 320 offspring, how many offspring would you expect to be homozygous recessive at both loci?

In mice, coat color is determined by two genes. Gene A controls the production of pigment, while Gene B determines whether the pigment is distributed throughout the coat. The dominant allele A allows pigment production, while the recessive allele a prevents it. The dominant allele B allows pigment distribution, while the recessive allele b prevents it. If a mouse has the genotype aaBB, what will its coat color be?
