Mention the total number of chromosomes along with the sex chromosomes that are present in a human female and male. Explain how in sexually producing organisms the number of chromosomes in the progeny remains the same as that of the parents.

Hii!!!!
In human males, the two sex chromosomes present are X and Y, while in human female, both sex chromosomes are X. During sexual reproduction, the new individual is formed by the fusion of gametes from both the parents. ... They are formed by the meiosis, a type of cell division which reduces chromosome number to half.
Hope you will understand...
Have a good day:):)
In male there are XY sex chromosomes and in female there XX
Both of them have 22pairs of Autosomes also. Whose one chromosome of 1 pair comes from father's side and other from mother's side.
Male:22pairs Autosomes and XY (1 pair of sex chromosome )
Female:22pairs Autosomes and XX (1 pair of sex chromosome)
Due to meiosis gametes are haploid so when they fuse they again form diploid zygote. Likewise no. Of chromosome remains same.
