The sexual reproduction process can be divided into three basic stages, viz.:<\/p>\n\n\n\n
This stage involves the formation of gametes (gametogenesis<\/em>) and the transfer of the gametes. Mature male parents produce male gametes (sperms) in male gonads in a process called spermatogenesis<\/em>. Mature female parents produce female gametes (ova) in female gonads in a process called oogenesis<\/em>. Gametes are produced from meiotic cell division; hence each gamete produced will be a haploid. <\/p>\n\n\n\n In most cases, male gametes are mobile and female gametes are immobile. Hence, for fertilization, there must be the transfer of the male gametes up to female gametes. It occurs during pollination in plants or sexual intercourse process in higher animals or by environmental factors like water in lower plants and animals. <\/p>\n\n\n\n It is the process of fusion of haploid male and female gametes (i.e. ovum and sperm) leading to the formation of a diploid zygote. It is the crucial difference between sexual and asexual reproduction. The asexual reproduction process lacks the fertilization process. Fertilization together with the meiotic division during gametogenesis regulates the chromosome number in sexual reproduction. <\/p>\n\n\n\n Fertilization may occur outside the female body, called\u00a0external fertilization. It is seen in fishes, some amphibians, crustaceans, echinoderms, algae, sponges, etc. It requires a water substrate for the transfer and fusion of gametes.\u00a0<\/p>\n\n\n\n In most higher animals and plants, fertilization occurs inside the female body. This is called internal fertilization<\/em>. It is seen in reptiles, some amphibians, insects, birds, mammals, higher plants, etc. <\/p>\n\n\n\n It is the process of the development of the zygote and the formation of a new individual. The zygote divides mitotically forming the embryo in a process called embryogenesis. The embryo will then develop into a fetus where organogenesis occurs leading to the production of an infant. The infant will grow and mature to continue the reproduction process. <\/p>\n","protected":false},"excerpt":{"rendered":" The sexual reproduction process can be divided into three basic stages, viz.: 1.
