WebApril 10, 2024. Sperm must swim swiftly to an egg in order to fertilize it, and so they have evolved hydrodynamic shapes. Most of the space in the head of sperm cells is taken up by the DNA they carry, so the cells coil up their DNA super tightly to stay small and streamlined. In most cell types, DNA is coiled around proteins called histones. Web1. Answer The human sperm is a gamete and it contains the haploid number of chromosomes.

The egg has 23, and the sperm has 23 (leading to 46 total, in 23 pairs) However, genetically, the sperm and egg each only have one. The egg has an "X" chromosome, and the sperm has either an "X" or a "Y" chromosome. So, that means they only have 1 chromosome each. the playground dothan alThe human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell with 46 paired chromosomes.
