The ratio of chromosome number between an egg and its zygote is 1:2. Sperm contains the genetic material from the father while the egg contains the genetic material from the mother. Sperm can either have X chromosome or Y chromosome but egg always have an X chromosome.
What would be the ratio of chromosome number between an egg and the zygote?
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.
What would be the ratio of chromosome number between an egg and its zygote Class 10?
In human beings, the egg cell is haploid while the zygote is diploid in nature. There are 23 chromosomes in an egg cell and 46 chromosomes in a zygote. Therefore, the ratio of chromosome number between an egg and a zygote would be 1:2.
What is the chromosome number of a normal human egg or sperm cell?
The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
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.
How is the 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.
