How are sperm cells and egg cells produced?

Both the egg and sperm cells are produced by Meiosis, which is a special type of cell division, where the cells only have half the number of chromosomes, one from each pair. When the process of Meiosis is complete, 4 cells are formed = eggs or sperm.

How sperm cells are formed?

Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells.

How is sperm genetically different from egg?

Sperms and eggs are genetically different in terms of nature of sex chromosome. The sperm contain either X or Y-chromosome whereas an egg will always have an X-chromosome.

How fertilization takes place in a woman?

Fertilization occurs in the fallopian tubes Fertilization takes place in the fallopian tubes, which connect the ovaries to the uterus. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote.

What is the difference between gamete and zygote?

Difference between Gamete and Zygote: Gametes are unfertilized reproductive cells. Zygote is a fertilised egg or a fertilised egg. As a product of meiosis, gametes are always haploid cells. Since zygote is the product of the fusion of the male and female gamete haploid, it is a diploid structure.

What would be the ratio of chromosome?

The chromosome number ratio between the egg and its zygote is 1:2. A female gamete with a haploid number of chromosomes is called an egg. It fuses with a male gamete (which also has a haploid number of chromosomes) during fertilization to form a zygote with a diploid number of chromosomes.

Can a woman run out of eggs?

Menopause occurs naturally when a woman’s ovaries run out of functioning eggs. At the time of birth, most females have about 1 to 3 million eggs, which are gradually lost throughout a woman’s life.
