Multiple Choice
All but one statement describes an advantage of meiosis. Which statement does NOT describe an advantage of meiosis?
A
Meiosis produces diploid gametes for sexual reproduction.
B
Meiosis allows for the repair of damaged DNA during recombination.
C
Meiosis reduces the chromosome number by half, preventing chromosome doubling in each generation.
D
Meiosis increases genetic variation among offspring.
Verified step by step guidance

Understand the purpose of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, producing haploid gametes (sperm and egg cells) for sexual reproduction. This ensures that when gametes fuse during fertilization, the resulting zygote has the correct diploid chromosome number.
Analyze the given statements: The problem provides four statements, three of which describe advantages of meiosis, while one does not. Your task is to identify the statement that does NOT describe an advantage of meiosis.
Evaluate the first statement: 'Meiosis produces diploid gametes for sexual reproduction.' Recall that meiosis produces haploid gametes, not diploid gametes. This statement is incorrect and does not describe an advantage of meiosis.
Evaluate the remaining statements: 'Meiosis allows for the repair of damaged DNA during recombination,' 'Meiosis reduces the chromosome number by half, preventing chromosome doubling in each generation,' and 'Meiosis increases genetic variation among offspring.' All of these are true and describe advantages of meiosis.
Conclude that the statement 'Meiosis produces diploid gametes for sexual reproduction' does NOT describe an advantage of meiosis, as it is factually incorrect. Meiosis produces haploid gametes, not diploid gametes.
