Explanation:
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.Mar 19, 2018

Answer:
Chromosomes are small thread like structures which contains genetical information, for the formation of new individuals.
In sexually reproducing organisms, the parental chromosomes interchange and undergo meiosis that divides into two segments, that form a complete pair of chromosome. In this way, the number of progeny is maintained
