Question 12

What is involved in the process of artificial selection?

Accepted Answer

Humans select animals to breed that create offspring with desired traits.

Answer

An animals' genes undergo a mutation that produces a certain trait.

Answer

Animals mate randomly, and a beneficial trait emerges in the offspring.

Answer

An organism with a beneficial trait is more likely to survive.

Question 13

Albinism is a recessive genetic condition in which a person lacks a pigment that gives color to the skin. If the allele for albinism is represented as "a" and the functional allele is represented as "A" what will be the genotype of a person with albinism?

Accepted Answer

aa

Answer

Aa or AA

Answer

Aa or aa

Answer

AA

Question 14

Polydactyly is an inherited condition common in cats. It causes cats to grow extra digits, or toes, on their paws. It is dominant over the characteristics to grow the normal number of digits. If a male cat that is heterozygous for polydactyly (Pp) mates with a female that is homozygous for polydactyly (pp), what are the possible genotypes of their first generation offspring?

Accepted Answer

Pp and pp, only

Answer

PP and pp, only

Answer

PP, Pp, and pp

Answer

Pp, only

Question 15

In a certain species of a plant, the allele for tallness is dominant over the allele for shortness. What type of plant should a tall plant be crossed with to determine whether it is heterozygous or homozygous?

Accepted Answer

a short plant

Answer

a medium-sized plant

Answer

a different species of plant

Answer

a tall plant

Question 16

A dog breeder selects only his best animals to breed. What is this process called?

Accepted Answer

artificial selection

Answer

natural selection

Answer

artificial variation

Answer

survival of the fittest

Question 17

Which statement best describes meiosis?

Accepted Answer

It produces gametes (eggs and sperm)

Answer

It produces cells identical to the parent cells.

Answer

It is carried out in all tissues.

Answer

It is the first stage of mitosis.

GG

Answer

Gg

Answer

gg

Answer

YY

Question 19

Cystic fibrosis occurs when offspring inherit a copy of the recessive allele (f) from each parent, thus having a genotype of (ff). People with genotype (Ff) do not suffer from cystic fibrosis but can pass it on to offspring. What is the likelihood, expressed as a percentage, of a child inheriting cystic fibrosis if both the parents have genotype (Ff)?

Accepted Answer

25%

Answer

50%

Answer

75%

Answer
