explain how in sexually reproducing organisms the number of chromosomes in progeny is maintained
ombhutkipdg479:
n sexually reproducing organisms, the gametes undergo meiosis, and hence, each gamete contains only half a set of chromosomes. When two gametes fuse, the zygote formed contains the full set of chromosomes. Hence, the formation of gametes by meiosis helps to maintain the number of chromosomes in the progeny.

Each cell have two copies of chromosome one inherited from each mother and father. Every germ cell is taking one chromosome from each pair that may from either maternal origin or paternal. When this two germ cell combine, they restore the normal no. of chromosome in the progeny maintaining the stability of DNA
