Question

PLEASE HELP!!
1.) In guinea pigs, rough fur (F) is dominant over smooth fur (f). What percent of the F2 generation would be homozygous dominant when a homozygous rough fur guinea pig is crossed with a homozygous smooth fur guinea pig?

2.)A person’s second toe is sometimes longer than their big toe. This condition is due to a dominant gene (L). What percent of the kids would you expect to have long second toes when a heterozygous man (Ll) marries a homozygous recessive woman (ll)?

3.)Facial dimples in man are dominant over no dimples. Show the expected children of a marriage between a w

1.) In guinea pigs, rough fur (F) is dominant over smooth fur (f). What percent of the F2 generation would be homozygous dominant when a homozygous rough fur guinea pig is crossed with a homozygous smooth fur guinea pig?
ans 3:1
3-rough fur
1-smooth fur

2.)A person’s second toe is sometimes longer than their big toe. This condition is due to a dominant gene (L). What percent of the kids would you expect to have long second toes when a heterozygous man (Ll) marries a homozygous recessive woman (ll)?
ans 1:1

Answer 2

1. ^ heena above is correct but the answer to your question is 25% would be homozygous dominant meaning a 1 out of every 4 offspring would be FF.

2. question 2 is 50% assuming there are no sex-linked heritability variables.
