Question

All of the following occur as a result of meiosis except:

a. chromosome number remains at 46.
b. primitive sex cells become mature gametes.
c. the cells become haploid.
d. meiosis occurs in two steps.

Answer 1

Meiosis results in a reduction of the chromosome number by half, resulting in haploid cells. The other provided options are incorrect.

Step-by-step explanation:

The correct answer is option a. Chromosome number remains at 46.

During meiosis, the number of chromosomes is reduced by half, resulting in haploid cells. In humans, the original cell has 46 chromosomes, and after meiosis, the four daughter cells each have 23 chromosomes.

The other options are incorrect:

• Option b is incorrect because primitive sex cells (also known as germ cells) become mature gametes through meiosis.
• Option c is incorrect because meiosis indeed results in haploid cells, which have half the number of chromosomes as the parent cell.
• Option d is incorrect because meiosis occurs in two main steps: meiosis I and meiosis II, each with specific phases.
