Question

which of the following best describes the process that results in the production of a normal human gamete?
one cell division produces four identical 1n cells.
two cell divisions produce four different 1n cells.
one cell division produces two identical 2n cells.
two cell divisions produce four different 2n cells.

Explanation:

Gametes are produced through meiosis. Meiosis involves two cell divisions (meiosis I and meiosis II). In meiosis I, homologous chromosomes separate, and in meiosis II, sister chromatids separate. Also, crossing - over occurs during meiosis I (prophase I), which leads to genetic variation. Human gametes are haploid (\(1N\)).

Answer:

Two cell divisions produce four different \(1N\) cells.
