WebApr 14, 2024 · Aneuploidy in preimplantation embryos is a major cause of human reproductive failure. Unlike uniformly aneuploid embryos, embryos diagnosed as diploid-aneuploid mosaics after preimplantation genetic testing for aneuploidy (PGT-A) can develop into healthy infants.

In the same generation, a number of green beetles were killed randomly when someone stepped on them and had no offspring. The next generation had more brown beetles than the previous generation — but just by chance.

There are many sources of genetic variability in a population: • Homologous recombination is a significant source of variability. During meiosis in sexual organisms, two homologous chromosomes cross over one another and exchange genetic material. The chromosomes then split apart and are ready to contribute to forming an offspring. Recombination is random and is governed by its own set of genes.
