Mention the total number of chromosomes along with the sex chromosomes that are present in a human female and a human male. Explain how in sexually producing organisms the number of chromosomes in the progeny remains the same as that of the parents.
There are 23 pairs (i.e. 46) of chromosomes present in human beings. In the male, 44 autosomes + XY Allosome and in the female, 44 autosomes + XX Allosome.
The humans have 46 chromosomes, the male has 46 chromosomes, and female has 46 chromosomes when they reproduce sexually then half of their chromosomes will go for progeny i.e. 23 chromosomes from male and 23 chromosomes from female will go for progeny. So progeny get 46 chromosomes totally. Therefore the number of chromosomes in the progeny remains the same as that of the parents.
