In human, Reproduction is done when two gametes i.e a sperm and an ovum fuse to give a zygote and eventually an offspring.
<h3><u>
Explanation:</u></h3>
Reproduction is the process by which a living organism can produce more individuals of same species to continue a race. Reproduction is of various types - asexual reproduction and sexual reproduction.
But in human, only sexual reproduction is seen. Here in human, males do produce sperms in their testis from the sperm mother cells by means of meiosis. Females do produce ovum in their ovary by means of meiosis from ovum mother cell.
Now the fertilization in human is internal fertilization which is achieved by means of coitus or sex between a male and female, where the male inserts his penis into female vagina to release the sperms. These sperms do swim into uterus and then into ampulla region of fallopian tube where it meets the ovum, and fertilization occurs. Then the zygote swims to uterus by passive movements and settle there which is called implantation. Then eventually the cell divisions lead it into a multicellular embryo and then after a gestation period of about 278 days, the baby is delivered. A new offspring is born.
