Quizplus · Accepted Answer

The 46 chromosomes in a human zygote come from the fusion of a sperm cell (which contains 23 chromosomes) and an egg cell (which also contains 23 chromosomes), resulting in the zygote having a total of 46 chromosomes. Therefore, half of the chromosomes come from the egg and half come from the sperm.
