Question

What is true about the formation of a meiotic spindle?

1) It forms once during meiosis I and once during meiosis II.
2) It forms once during meiosis.
3) It forms once during meiosis in males, and twice during female meiosis.
4) It forms once during meiosis in females, and twice during male meiosis.
5) E.) It forms in viable gametes with a haploid complement of chromosomes.

Answer 1

The formation of a meiotic spindle differs between males and females during meiosis, with females forming the spindle once and males forming it twice.

Step-by-step explanation:

The correct answer is option 3) It forms once during meiosis in males, and twice during female meiosis.

In meiosis, a spindle forms during prophase I. This spindle helps separate the homologous chromosomes during anaphase I. In males, meiosis consists of two rounds of cell division, resulting in the formation of four haploid cells called spermatids. Each spermatid eventually develops into a mature sperm. In females, meiosis also consists of two rounds of cell division, but only one of the resulting cells becomes a functional egg, while the other three cells called polar bodies degenerate.

Therefore, option 3) is true about the formation of a meiotic spindle.
