1.	Gametogenesis is the phenomenon known for the formation of haploid gametes taking place in both males and females. Observe the flowchart given below highlighting the influence of process of gametogenesis and answer the questions that follows.(1) Identify the type of gametogenesis shown and in whom does it take place?(2) Explain the role of different hormones involved in the complete process
Answer» (1) The process shown in the figure above is oogenesis. It is a type of gametogenesis which occurs in females. (2) The hormones involved in the process of oogenesis in females similar to those involved in the process of spermatogenesis in males with a only difference, that is, oogenesis hormones acts on ovaries to stimulate the complete process. The process of gametogenesis (oogenesis) in females begins from the part of the brain, (called hypothalamus) which releases a hormone called gonadotropin releasing hormone or GnRH that further stimulates the release of hormones to act on gonads.In female, Follicle stimulating hormone acts on anterior pituitary which stimulates the folliciles present in the ovary containing the developing eggs. It also stimulates the ovary to produce the hormone, called oestrogen. This leads to the development of secondary sexual characteristics including the development of breasts and deposition of fat in some places. It also signals a drop in FSH and the production of LH (Leutinising hormone). This LH further causes the process of ovulation (i.e. the release of the egg in the females).
