Question

How does reproduction occur in humans?

Answer 1

Human reproduction is any form of sexual reproduction resulting in human fertlization, typically involving sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the and female reproductive system results in fertilization of the woman's ovum by the man's sperm. These are specialized reproductive cells called gamates, created in a process called meiosis. While normal cells contains 46 chromosomes, 23 pairs, gamete cells only contain 23 chromosomes, and it is when these two cells merge into one zygote cell that genetic recombination occurs and the new zygote contains 23 chromosomes from each parent, giving them 23 pairs. After a gestation period, typically for nine months, is followed by choldbirth. The fertilization of the ovum may be achieved by artificial insemination methods, which do not involve sexual intercourse.
