Complete the Punnett square as shown in the "Show Your Work" below in order to gain full credit.

What percentage of offspring would be heterozygous?

Complete the Punnett square as shown in the "Show Your Work" below in order to gain full credit.

What percentage of offspring would be homozygous dominant?

Complete the Punnett square as shown in the "Show Your Work" below in order to gain full credit.

What percentage of offspring would be homozygous dominant?

Asemmisa {{asɛmmisaAhyɛnsode}}
15.

Complete the Punnett square as shown in the "Show Your Work" below in order to gain full credit.

What percentage of offspring would be homozygous recessive?

Asemmisa {{asɛmmisaAhyɛnsode}}
16.

Complete the Punnett square here for full credit. Use H and h for the allele for hair. Short hair (H) is dominant over long hair (h).

One parent is heterozygous for short hair and one is homozygous for long hair. Be sure to type the parent alleles outside the box.

What percent of the offspring will have short hair?

Asemmisa {{asɛmmisaAhyɛnsode}}
17.

Complete the Punnett Square for full credit this time for two parents that are heterozygous. Use H for dominant short hair and h for recessive long hair again. Be sure to type the parent alleles outside the box.

What percent of the offspring will have short hair?
