Multiple Choice

How many chromosomes are in a haploid human cell?

Previous problemNext problem

Verified step by step guidance

Understand the concept of haploid and diploid cells: In humans, diploid cells contain two sets of chromosomes, one from each parent, totaling 46 chromosomes. Haploid cells, such as gametes (sperm and egg cells), contain only one set of chromosomes.

Identify the type of cell in question: The problem asks about a haploid human cell, which is a gamete.

Recall the number of chromosomes in a haploid cell: Since haploid cells have one set of chromosomes, they contain half the number of chromosomes found in diploid cells.

Calculate the number of chromosomes in a haploid cell: Divide the total number of chromosomes in a diploid cell (46) by 2 to find the number in a haploid cell.

Conclude with the correct number of chromosomes in a haploid human cell: The result of the division gives the number of chromosomes in a haploid cell, which is 23.
