People are Dioecious i.e. consist of female and male gonads in various induviduals.Male Gonads produce sperms and the female gametes produce Ovum. Lower animals advertisement plants are generally Monoecious.
The chromosomes which assist in option of the sex of the offspring are called the Allosomes or Sex Chromosomes. Whereas the vegtative chromosomes which are not helpful in sex are called the Autosomes.
The technique of sex option in Human Beings is XY type, where in males, the Allosomes are XY type and in women the allosomes are XX
type. People include 46 chromosomes in the nucleus of the cell out of which, 44 are autosomes and other 2 are allosomes.
On production of gametes, the no. of chromosomes is reduced to half, i.e. in the gametes there are 23 chromosomes. The sort of chromosomes is not very specific very same.
In women, ova includes 22 autosomes and 1 X chromosome.
In males, the sperm consists of 22 autosomes as in ovum nonetheless the allosome can be either X or Y type, i.e. a sperm can include either X or Y alloome.
Throughout fertilisation, if sperm with X allosome merges with the ovum, then it results into improvement of female offspring (XX) and if Y allosome of male merges with the ovum, then it results to the improvement of Male offspring (XY).
Ovum has no function in sex option nonetheless the sperm has the function of sex option in people, i.e. if sperm has X allosome, offspring is female and if Y allosome exists, offspring if male.
On production of gametes, the no. The type of chromosomes is not accurate really exact same.
On production of gametes, the no. The kind of chromosomes is not exceptionally precise very same.
On production of gametes, the no. The kind of chromosomes is not incredibly precise very same.
