because in sexual reproduction, gametes form in haploid condition , which then fuse to form a diploid zygote.if the number of chromosomes changes, a new species is formed . in asexual reproduction, usually amitosis, fragmentation and budding , there is a lesser chance of this happening . this can be illustrated by the wider range of sexually reproducing organisms, which are higher in the evolutionary line, than the asexually reproducing organisms which are in the bottom of the evolutionary line. if the number of chromosomes does not change during meiosis and zygote formation, number of chromosomes are retained as the same process occurs in several generations . there are also certain chemicals thst regulate the process of mitosis and meiosis that supervise the number of chromosomes
