Chromosomes and genes do not double in each generation in se-xual reproduction because they are usually halved before being donated to offspring.
What is meiosis?
Meiosis is a reductional division involving s-ex cells. Meiosis happens prior to se-xual reproduction.
In other words, the halving of chromosomes takes place during the formation of gametes. Thus, gametes usually carry half of the chromosome and only a copy of each gene of the parents.
When two gametes combine to result in a zygote, their chromosomes and genes also pair up to arrive at a normal number of chromosomes and genes.
