Dihybrid Crosses and Gene Linkage AHL Topic 10.2 Topic 4.3

Let’s Practice Widows Peak= dominant (W) Dimples= dominant (D) Cross a woman that is homozygous dominant for both traits with a man that is homozygous recessive for both traits. Woman’s genotype = Woman’s gametes = Man’s genotype = Man’s gamete =

Phenotypes of offspring= Cross a woman that is heterozygous for both traits with a man that is homozygous dominant for both traits. Woman’s genotype = Woman’s gametes = Man’s genotype = Man’s gamete =    Phenotypes of offspring=
