Multiple Choice

In humans, how many chromosomes do body cells typically have after meiosis?

Verified step by step guidance

Understand the process of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four daughter cells, each with half the number of chromosomes of the parent cell.

Recognize the difference between body cells and gametes: Body cells, also known as somatic cells, have a full set of chromosomes, while gametes (sperm and egg cells) have half the number of chromosomes.

Identify the chromosome number in humans: Humans typically have 46 chromosomes in their body cells, which is the diploid number. This includes 23 pairs of homologous chromosomes.

Consider the result of meiosis: Meiosis produces gametes with a haploid number of chromosomes, which is 23 in humans. These gametes combine during fertilization to form a zygote with 46 chromosomes.

Clarify the context of the question: The question asks about the chromosome number in body cells after meiosis. Since meiosis results in gametes, the body cells themselves remain with 46 chromosomes, as they are not directly involved in meiosis.
