Is There any way in which a currently living could be
mutated in reality to such a large scale as to which others
could see the mutation, such as a third arm?

Is Genetic Engineering worth the cost and effort?

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?

Flower position, stem length, and seed shape were three
traits that were studied by Mendel. Each is controlled by
an independently assorting gene. If a plant that is
heterozygous for all three traits was allowed to self-
fertilize, what proportion of the offspring would be
expected to show all three dominant phenotypes?

In horses coat color is dependent upon genes as follows:
A_B_ results in bay, aaB_ in black, A_bb in chestnut, aabb
in liver. In addition, palimino is derived by Dd with
chestnut. A palimono stallion (DdAAbb) is crossed with a
palimino mare (DdAAbb). What percent of the offspring will
be palimino?

The rare trait of ocular albinism (almost complete absence
of eye pigment) is inherited as a sex-linked recessive. A
man with ocular albinism marries a woman who neither has
this trait nor is a carrier. What would you predict about
their offspring concerning this trait?

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?

Suppose a father of blood type B and a mother of blood type
O have a child of type O. What are the chances that their
next child will be blood type O? Type B? Type A? Type AB?
