Use the chart below to identify the phenotype of a snail with the genotype WwPpbb

1

Use the chart to determine the genotype of a snail that is recessive for shell color, heterozygous for skin color, and homozygous dominant for eyes.

A scientists is studying the inheritance of two genes, gene B and gene H, in dogs. Each gene is located on a different chromosome. Gene B has two alleles, B and b, and gene H has two alleles, H and h. What are the expected probabilities for the genotypes of gametes produced by a dog with the genotype BbHh?
