In dogs, a dominant gene (W) produces wire-haired texture. The recessive allele (w) produces smooth hair. A homozygous wire-haired male is mated to a female with smooth hair. Show the punnett square. What genotypes and phenotypes are expected in the F1 generation, and in what ratios?
This will be done on the board.

In humans, brown eyes (B) are dominant over blue (b)*. A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one of whom is blue-eyed. Draw the Punnett square that illustrates this marriage. What is the man’s genotype? What are the genotypes of the children?
