Chapter 2, Problem 4P
In mice, black coat color is dominant to white coat color. In the pedigree shown here, mice with a black coat are represented by darkened symbols, and those with white coats are shown as open symbols. Using allele symbols B and b, determine the genotypes for each mouse.

The pedigree concerns eye phenotypes in Tribolium beetles. The solid symbols represent black eyes, the open symbols represent
brown eyes, and the cross symbols (X) represent the "eyeless" phenotype, in which eyes are totally absent.
Assume that these three phenotypes are the result of three alleles of a single gene, E, where E' is black, g? is brown, and
is eyeless.
Assign a genotype to each individual in generation II.

In dogs, dark coat color phenotype (D) is dominant over albino (a) and short hair (S)
is dominant over long hair (I). Assume that these phenotypes are caused by two
independently assorting genes and write as much as you can, the genotypes of the
parents in the cross below. D, a, S and I represent phenotypes
Y indicates the presence of progeny with this phenotype, whereas N indicates the
