WebFertilization leads to new, diploid offspring. Sexual reproduction results in genetic variation, or genetic differences, between parents and offspring. Offspring inherit one set of chromosomes from each parent.

Different fertilization practices lead to the enrichment of specific bacteria or fungi that can efficiently use these nutrients, thus changing the composition of the microbial community. ... WebFertilization is a process that involves the fusion of two haploid gametes, one from the male and the other from the female, resulting in the formation of a diploid cell called a zygote. Therefore, fertilization results in a diploid cell. The zygote contains a complete set of chromosomes, half from each parent, which provides the genetic ... how to sort gmail emails by date
