A heterozygous white rabbit is crossed with a homozygous black rabbit. On a sheet of paper, list the parent genotypes; draw and fill and Punnett square, and then list the offspring genotypes and phenotypes.
genotype: 25% heterozygous; 75% homozygous recessive
phenotype: 50% white and 50% black
genotype: 50% heterozygous; 50% homozygous recessive
phenotype: 50% white and 50% black
