WebOver time, if this imbalance persisted, natural selection would favor females with genetically variable litters — and hence, females who engaged in multiple matings. So perhaps, what we humans perceive as promiscuity is actually an adaptation that allows female cheetahs to increase the odds of having at least one cub survive to pass on her genes.

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. Being controlled by genes m… the tall dwarfsWebThe same reasoning applies at the population level.
