Question

how does recombination contribute to offspring diversity?
□ it yields gametes with random combinations of maternal and paternal chromosomes.
□ it modifies chromosomes to generate new alleles of genes that code for proteins.
□ it increases the genetic diversity among gametes produced by an organism.
□ it yields chromosomes that contain both maternal and paternal dna.
□ it generates gametes with selective advantages over the gametes of competitors.

Explanation:

• Option A: During recombination (cross - over in meiosis), maternal and paternal chromosomes exchange genetic material, leading to random combinations in gametes.
• Option C: By creating new combinations of alleles, recombination increases genetic diversity in gametes.
• Option D: Recombination results in chromosomes (in gametes) that have segments from both maternal and paternal DNA.
• Option B: Recombination does not modify chromosomes to generate new alleles (mutation does that, not recombination).
• Option E: Recombination is a random process and does not specifically generate gametes with selective advantages over competitors' gametes.

Answer:

A. It yields gametes with random combinations of maternal and paternal chromosomes.
C. It increases the genetic diversity among gametes produced by an organism.
D. It yields chromosomes that contain both maternal and paternal DNA.
