Question

Which of the following events causes recombination between linked genes to occur? Group of answer choices a)When genes are linked they always "travel" together at anaphase. b)Crossovers between these genes result in chromosomal exchange. c)Mutation on one homolog is different from that on the other homolog. d)Nonrecombinant chromosomes break and then re-join with one another.

Answer 1

Answer:

b)Crossovers between these genes result in chromosomal exchange. d)Nonrecombinant chromosomes break and then re-join with one another.

Explanation:

Answer 2

The event that causes recombination between linked genes is 'crossovers between these genes result in chromosomal exchange' (Option b).

Linked genes are genes localized on the same chromosome.

Moreover, cross-over, also known as recombination, refers to the exchange of genetic material between non-sister chromatids during Meiosis I (i.e., Prophase I).

Recombination is a genetic mechanism that allows the generation of new allele combinations between linked genes.

In conclusion, the event that causes recombination between linked genes is 'crossovers between these genes result in chromosomal exchange' (Option b).
