Dihybrid Crosses

Master dihybrid crosses with our genetics worksheet! Solve Punnett squares and predict offspring traits.

Use the following information to finish the dihybrid cross. A blonde haired blue eyed female and a brown haired brown eyed male want to know the possibility of have a child with blonde hair and blue eyes. The male only has blonde hair in his family as well as blue eyes. Use H for hair and B for eyes HB Hb hB hb hb HhBb Hhbb hhBb hhbb hb HhBb Hhbb hhBb hhbb hb HhBb Hhbb hhBb hhbb hb HhBb Hhbb hhBb hhbb From the dihybrid cross above, what percent chance will the offspring have blonde hair and blue eyes? 10 % 25% 50% 75% Another couple examines their traits. The mother is homozygous dominant for hair and heterozygous for eyes, while the father is homozygous recessive for hair and heterozygous for eyes. Which of the following is the correct genotypes for the parents? HHBb; HhBb HHBB; HHBb HHBb; hhBB HHBb; hhBb From the questions above, match the gamete to the correct parent. HB Mother hB Father
