Answer / margaret
If the dominant normal gene is A, and the recessive albino
gene is a, then the man's genotype is
Aa

Answer / prussian embassy
To correctly answer the question, the normally pigmented
man would be "Aa": A for his dominant trait of normal
pigmentation, and "a" for the gene of albinism.
Reasons supporting this answer are this; for a recessive
trait to show itself by any means, it would need to be the
only factors in the gene. Together, they look something
like this.
A x
,-------
a |Aa |ax |
|___|___|
|Aa |ax |
a |___|___|
The genotype of the children are Aa, Aa, and aa.
For there to be a posibility of having a child albino, the
normally pigmented man must have the ressesive gene.
Therefore turning the chart above into this.
A a
,-------
a |Aa |aa |
|___|___|
|Aa |aa |
a |___|___|
In the end, it proves that the normally pigmented man's
genotype is "Aa": A for his dominant trait of normal
pigmentation, and "a" for the gene of albinism.

Answer / taofeeq
The genotype of the man is Aa (He is a carrier of the gene
for albinism(a). The Child can only express the trait when
he/she inherits the albinism gene(a). The child genotype
will then ber aa.

A blastomere was removed from an 8-cell human embryo, and its beta-globin gene was amplified by PCR. The beta-globin DNA was treated with an enzyme that cuts on either side of and within the normal allele (producing a small fragment), but not within the sickle cell allele (producing a large fragment). Electrophoresis of the treated DNA from the blastomere demonstrated the presence of both a large and small fragment derived from the beta-globin genes. How should you interpret this test?
In hogs a gene that produces a white belt around the animal's body is dominant over its allele for a uniform body. Another independent dominant gene produces fusion of the hoof (syndactyly). Suppose a uniformly colored hog homozygous for syndactyly is mated with a normal footed hog homozygous for the belted character. What would be the phenotype of the F1? If the F1's interbreed, what would be the phenotypic ratio of the F2?
