question 8 of 10
a cow is heterozygous for black coat color, which is dominant over red coat
color. which statement describes the movement of the cows alleles during
meiosis, according to the law of segregation?
a. an allele for the black coat trait moves into one gamete, and an
allele for the red coat trait moves into the other gamete.
b. an allele for the black coat trait and an allele for the red coat trait
together move into each gamete.
c. one allele for the red coat trait moves into each gamete.
d. one allele for the black coat trait moves into each gamete.

Explanation:

According to the law of segregation, during meiosis, the two alleles of a gene (in this case, for coat color) separate. A heterozygous cow (with one allele for black - dominant and one for red - recessive) will have these alleles segregate. Each gamete gets one allele. So, one gamete gets the black allele and the other gets the red allele. Option B is wrong as alleles do not stay together in gametes during segregation. Options C and D are incorrect because both alleles (not just one type) are involved in the segregation process for a heterozygous individual.

Answer:

A. An allele for the black coat trait moves into one gamete, and an allele for the red coat trait moves into the other gamete.
