Which describes a mature sperm in terms of the number of chromosomes it contributes during reproduction?
diploid with 46 chromosomes
haploid with 46 chromosomes
diploid with 23 chromosomes
haploid with 23 chromosomes

haploid with 23 chromosomes

Explanation:

Sperm are generally cells, much smaller than eggs and are structured to allow maximum displacement efficiency, which increases the chance of them reaching the egg. They are small, elongated cells with a hydrodynamic shape and with a long tail that is used in propulsion.

As you know, sperm is a reproductive cell and like every reproductive cell it contains half the chromosomes of a diploi cell. For this reason, we can say that spematozoids are haploid cells with 23 chromosomes.
