Question

5. According to Mendel’s law of segregation, which of the following statements describes what happens to the alleles of a gene pair?
A) The alleles are moved to different chromosomes.
B) The alleles are mutated in the process of mitosis.
C) The alleles are separated during fertilization.
D) The alleles are separated during gamete formation.

Answer 1

Answer:

D) The alleles are separated during gamete formation.

Explanation:

Gregor Mendel is regarded as the "Father of Genetics" due to his immense discovery of the principles that governs inheritance. One of those principles is explained in his LAW OF SEGREGATION, which states that alleles of a gene will separate into gametes in equal proportions.

According to this law, during gamete formation or meiosis, the separation occurs in such a way that one of the pair of alleles of a gene will be present in each gamete. For example, in a gene Rr, the gametes will either contain allele R or allele r in an equal proportion (50-50).
