Sex Decision In Humans

People are Dioecious i.e. include male and female gonads in various individuals.Male Gonads produce sperms and the female gametes produce Ovum. Lower animals advertisement plants are normally Monoecious.The chromosomes
which assist in decision of the sex of the offspring are called the Allosomes or Sex Chromosomes. Whereas the vegtative chromosomes which are not valuable in sex are called the Autosomes.The technique of sex decision in Humans 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 from which, 44 are autosomes and other 2 are allosomes.On production of gametes, the no.
of chromosomes is minimized to half, i.e. in the gametes there are 23 chromosomes. However the kind of chromosomes is not same.In women, ova includes 22 autosomes and 1 X

chromosome.In males, the sperm includes 22 autosomes as in ovum however the allosome can be either X or Y type, i.e. a sperm can include either X or Y alloome.During fertilisation, if sperm with X allosome merges with the ovum, then it results into development of female offspring(XX)and if Y allosome of male merges with the ovum, then it leads to the development of Male offspring (XY ).|The type of chromosomes is not same.In women, ova includes 22 autosomes and 1 X

Therefore, Ovum has no function in sex decision however the sperm has the function of sex decision in humans, i.e. if sperm has X allosome, offspring is female and if Y allosome exists, offspring if male.|Lower animals advertisement plants are normally Monoecious.The chromosomes

Therefore, Ovum has no function in sex decision however the sperm has the function of sex decision in human beings, i.e. if sperm has X allosome, offspring is female and if Y allosome is present, offspring if male.
