Question

What is the female Homogametic system?

Answer 1

Animals of heterogametic sex have two different sex chromosomes, allowing them to produce two different types of gametes. Members of the homogametic sex, on the other hand, can only produce one type of gamete. Males have one X and one Y chromosome, while females have two X chromosomes in humans (and many other animals). In butterflies and moths, this system is reversed.

Complete answer:
The ZW sex-determination system is a chromosomal system that determines the sex of offspring in birds, some fish and crustaceans like the giant river prawn, some insects (including butterflies and moths), the schistosome family of flatworms, and some reptiles like snakes, lacertid lizards, and monitors like Komodo dragons.
It's also found in some plants, where it's likely evolved several times. This system is distinguished from the XY sex-determination system by the letters Z and W. Females have two dissimilar ZW chromosomes, while males have two similar ZZ chromosomes in this system.
The sex of a species in which the sex chromosomes are not the same is known as heterogametic sex (digametic sex). Males with an X and a Y chromosome, for example, are known as the heterogametic sex, while females with two X chromosomes are known as the homogametic sex.
Random fusion of gametes occurs during fertilization. When 22A+X sperm fuses with 22A+X eggs, the zygote will have 44A +XX condition. A female child is born from such a zygote. When a sperm with the 22A+Y complement combines with an egg, the zygote has 44A+XY. As an example, a zygote can develop into a male child.
As a result, a specific male-to-female ratio is maintained in the global population. The female homogametic and male heterogametic systems have a chromosomal sex determination mechanism known as the XX – XY mechanism.

Note:
Males in birds and some reptiles, on the other hand, have two Z chromosomes and are homogametic, whereas females have one Z and one W chromosome and are heterogametic. Male platypuses are heterogametic, whereas female platypuses are homogametic. Lepidopterans (butterflies and moths) have heterogametic females, but males are the heterogametic sex in Drosophila.
