The two-fold cost of sex was first described by John Maynard Smith. If each individual were to contribute to the same number of offspring twoa the sexual population remains the same size each Darwins nightmare, where the b Asexual reproduction population doubles in size each generation.

Although sexually favoured, traits such as cumbersome antlers, mating calls, large body size and bright colours often attract predation, which compromises the survival of individual males.

The dress had a low neckline and no sleeves. Episode 3 Zero Two has one memorable moment. But even one-off traumas could affect later generations too. Genetic drift may therefore eliminate some alleles from a population due to chance alone. There were no black boxes in your car to tell government agents about your driving habits.

Genetic drift is the random fluctuations of allele frequencies within a population from one generation to the next. How do they help genes work, or stop working?
