b. homozygous.
c. heterozygous.
d. dominant.
Answer:
B. Homozygous
Explanation:
Homozygous organisms have two identical alleles for a trait. They may have two copies of dominant alleles or two copies of the recessive allele of a gene. For example, both RR and rr are homozygous genotypes. However, a heterozygous or hybrid genotype has one dominant and one recessive allele for a gene. Here, "Rr" genotype would be an example of hybrid or heterozygous genotype.
In genetics, organisms with two identical alleles for a specific trait are considered 'homozygous'. These can be either homozygous dominant or homozygous recessive, with the distinction depending on the specific alleles that are identical.
Organisms that have two identical alleles for a particular trait are said to be b. homozygous. This term is used in genetics, the branch of biology, for discussing the inheritance of traits. In this case, the two alleles inherited from parent organisms, one from each, are identical. For example, if a plant genotype is AA or aa for a specific trait, like height, it is considered homozygous, either homozygous dominant (AA) or homozygous recessive (aa).

D. based on creative impulses and insights that are unique to each other
A man with a widow�s peak and normal color vision marries a color-blind woman with a straight hairline.
The man�s father had a straight hairline, as did both of the woman�s parents.
Use the family history to make predictions about the couple�s children.
Drag the correct label to the appropriate location in the table. Not all labels will be used.

Based on the exercise data we know that the couple genotype for red-green color blindness is:
(XY x X'X')
X' X'
X X'X X'X
Y X'Y X'Y
And the genotypes for widow's peak are:
(Aa x aa)
a a
A Aa Aa
a aa aa
1) What is the chance that any daughter the couple has will be color blind with a straight hairline?
Zero
2) What is the chance that any son that the couple has will be color blind with a widow's peak?

3) If the couple has a child, what is the chance that it will be a daughter with a widow's peak?
1/4
4) Suppose the couple had a daughter with normal color vision and a widow's peak. What is the chance that she is homozygous for both genes?
Zero
