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.
Answer:
The total number of chromosomes present in both human females and males are 46 .
In human males, the 2 sex chromosomes found are X or Y , whereas in human females, both the sex chromosomes are X.
During sexual reproduction, the male gamete fuses with the female gamete and forms a zygote. A zygote is diploid ie., it contains 23 chromosomes from the mother and 23 chromosomes from the father . In this way, an equal genetic contribution of male and female parents is ensured in the Progeny.
