Question

question 33
a carrier is someone who _.
a expresses a recessive disease.
b expresses a dominant disease.
c has two copies of a recessive allele.
d will pass on a recessive disease to all of their children.
e has one copy of a recessive allele and one copy of a dominant allele for a particular gene.
question 34
which describes a genotype heterozygous for a single trait?
a aabb
b aabb
c aa
d aa
e aa

Explanation:

For Question 33, a carrier in genetics has one copy of a recessive allele and one copy of a dominant allele for a particular gene and does not express the recessive - linked disease. For Question 34, a heterozygous genotype for a single trait has two different alleles for that trait. In the given options, Aa represents a heterozygous genotype for a single trait.

Answer:

Question 33: E. has one copy of a recessive allele and one copy of a dominant allele for a particular gene.
Question 34: D. Aa
