1. Testes
Meiosis formation of male gametes (sperm) occurs in the testes of animals, while meiosis formation of female gametes (eggs) occurs in the ovaries. These structures are specialized for the production and maturation of sex cells through the process of meiosis.
It is still called meiosis, except that instead of an egg you end up with a sperm cell.
The female structure that is homologous to the testes are the ovaries in females. Both function in the production of gametes.
The pituitary gland secretes FSH and LH. FSH is in charge of stimulating the gonads to produce the gametes (eggs and sperms). However, in males testosterone is needs to produce "good" sperm. LH stimulates a specific group of cells called Leydig cells (intersitial cells) to produce testosterone.
Isogamy is a type of sexual reproduction where gametes of two different mating types are similar in size and structure. In isogamy, both gametes are capable of moving towards each other to fuse and form a zygote. This is in contrast to anisogamy, where the gametes are of different sizes and types.
Meiosis formation of male gametes (sperm) occurs in the testes of animals, while meiosis formation of female gametes (eggs) occurs in the ovaries. These structures are specialized for the production and maturation of sex cells through the process of meiosis.

gametangia
A gametangium is a structure in fungi, algae, and some plants that produces and encloses gametes for sexual reproduction. It can contain male gametes (sperm) or female gametes (eggs) or both. Gametangia are often specialized structures that allow for the fusion of gametes to create a zygote.
No, human gametes are not isogamous. Isogamy refers to the fusion of gametes that are similar in size and structure, whereas human gametes (sperm and eggs) are anisogamous, with sperm being much smaller and structurally different from eggs.
Gametes in human females typically stop maturing at menopause, which usually occurs around the ages of 45-55. At this point, there is a depletion of the ovarian follicles, leading to a cessation of ovulation and the maturation of eggs.
No, pollen and ovules are not gametes. Pollen is a male reproductive structure that contains sperm cells, while ovules are female reproductive structures that contain egg cells. Gametes are the actual sperm and egg cells involved in sexual reproduction.
An antheridium is a structure in plants that produces and releases male gametes, such as sperm cells. These male gametes are involved in the process of sexual reproduction by fertilizing female gametes to form a zygote.
It is still called meiosis, except that instead of an egg you end up with a sperm cell.
The spleen is a structure that is not involved in the production or delivery of gametes. It is part of the lymphatic system and plays a role in filtering blood, storing red blood cells, and helping the immune system fight infections.
The female structure that is homologous to the testes are the ovaries in females. Both function in the production of gametes.
The offspring produced by the fusion of gametes from two different sources is a genetically unique individual with a combination of traits from both parents. This process promotes genetic diversity within a population and contributes to evolution through natural selection.
