A human zygote is diploid and it has 46 chromosomes. Fertilization results in 46 chromosomes in the human zygote which is the regular number of chromosomes of a somatic cell of a human. In single-celled organisms the zygote can divide asexually by mitosis to produce identical offspring. The zygote contains two sets of 23 chromosomes for the required 46. Become a member and unlock. See full answer below.
During fertilization gametes from the sperm combine with gametes from the egg to form a zygote.
Come together the resulting fertilized egg is called a ZYGOTE Zygotes are diploid and have the total 46 chromosomes in humans. If the sperm and egg each had 46 chromosomes the zygote would have 92. Come together the resulting fertilized egg is called a ZYGOTE Zygotes are diploid and have the total 46 chromosomes in humans. The secondary oocyte contained 23 chromosomes and the sperm cell contained 23 chromosomes. The origin of the 46 chromosomes in a human zygote is half from the sperm and half from the egg. You developed from the zygote by mitosis.
