Question

Difficulty: MediumGenetics and Heredity

In humans, mature gametes produced through meiosis are diploid cells that each contain 46 individual chromosomes.

Answer: Answer

Answer

False
The statement is false because human gametes (sperm and egg cells) are haploid, containing 23 chromosomes rather than the diploid count of 46 found in somatic body cells.

Step-by-Step Solution

1
Analyze the claim regarding the ploidy level and chromosome count of human gametes.
The statement asserts that human gametes (sperm and egg) are diploid and contain 46 chromosomes.
Accurate evaluation requires distinguishing between somatic body cells and reproductive cells.
2
Determine the effect of meiosis on chromosome number during gametogenesis.
Meiosis is a reductional division that halves the chromosome number from diploid (2n=462n = 46) to haploid (n=23n = 23).
This reduction ensures that when a sperm (2323) fertilizes an egg (2323), the resulting zygote receives the correct species chromosome number (4646).
