Homework Answers
True, it is a recessive trait because female is affected so she
must be homozygous recessive. And it skips generations. In the 4th
generation two individuals are affected that means their parents
must have been carriers. So if two of the parents are heterozygous
carriers the 50% chance offsprings are affected
So out of four ,two are affected.

1) Select the true statements about dominant and recessive genes, assuming complete penetrance of the genotype. Circle all that apply. (1.5) For an offspring to be phenotypically dominant for a trait, at least one parent will show the trait. For an offspring to be phenotypically recessive for a trait, at least one parent will show the trait. In incomplete dominant or codominant traits, heterozygotes will have a different phenotype than either homozygote. If both parents show a recessive trait, then...

A human trait that is caused by an autosomal dominant mutant allele has a penetrance of 50%. A man who is heterozygous for this mutant allele marries a woman who is homozygous recessive for the normal allele. If they have two children then what is the probability that both children will show the normal phenotype? O 1/4 o 1/2 03/16 0 7/8 09/16

1. Polydactyly is a dominant trait with about 63% penetrance. A pregnant woman is heterozygous for the dominant allele, but does not have extra toes or fingers. Her partner does not have polydactyly and is known to be homozygous recessive for the polydactyly gene. What is the probability that their child will be born with polydactyly? 4p
