Reproductive System
What is the chromosome complement of a sperm?
46 chromosomes (23 pairs including a pair of Y chromosomes)
46 chromosomes (22 pairs plus one X chromosome and 1 Y)
23 chromosomes including 1 X chromosome OR 1 Y
23 chromosomes including 1 X chromosome AND 1 Y
23 chromosomes including 1 X chromosome OR 1 Y
Sperm are haploid (have 23 chromosomes) so that when they fuse with the egg (also with 23 chromosomes), the zygote has 46 chromosomes. The X or Y chromosome of the sperm, in conjunction with the X of the egg, then determines the sex of the baby.
