Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm. Each gamete contains half the number of chromosomes of normal cells.

REPRODUCTION IN HUMAN BEINGS:
*the male gamete sperm is introduced inside the female genital tract vagina by the process of copulation or mating.fertilization occurs in the fallopian tubes
*sperms are highly active and mobile which move up through cervix into the uterus and then pass into the fallopian tubes.
*in the fallopian tube only one sperm fertilizes the ovum to form a zygote.this is called fertilization.
*fertilization only if copulation takes place during the ovulatory period..
*the embroyonic development of the zygote starts immediately in the fallopian tube and pregnancy starts and menstruation stops.
*the embryo moves down to reach the uterus.the embedding of embryo in the thick inner lining of the uterus is called implantation.
*then a special tissue develops between the uterine wall and the embryo called placenta where the exchange of nutrients ,oxygen and waste products takes place.
*the time period from the development of foetus inside the uterus till birth is called gestation.
*the act of giving birth to the fully developed foetus at the end of gestation period is called parturition.
*the development of the child inside the mother's body take approximately 9 months.
