selection /se·lec·tion/ (sĕ-lek´shun) the play of forces that determines the relative reproductive performance of the various genotypes in a population.
directional selection selection favoring individuals at one extreme of the distribution. disruptive selection , diversifying selection selection favoring the two extremes rather than the intermediate. natural selection the survival in nature of those individuals and their progeny best equipped to adapt to environmental conditions. sexual selection natural selection in which certain characteristics attract male or female members of a species, thus ensuring survival of those characteristics. stabilizing selection selection favoring intermediate phenotypes rather than those at one or both extremes.
sexual selection, the selection of mates on the basis of the attraction of or preference for certain traits, such as coloration or behavior patterns, so that eventually only those particular traits appear in succeeding generations. It explains the wide variety of sexual characteristics among the various species. Want to thank TFD for its existence?

If we can identify this gene or genes, we can say conclusively how they influence both color and mate choice," said Kronforst. It makes sense to use symmetry variation in mate choice," said evolutionary biologist Randy Thornhill, of the University of New Mexico. Topics of the research and review papers include Nijmegen Breakage Syndrome, models of genetic and physiological heterogeneity, polymorphisms in CCR5 chemokine receptor genes, genetic anticipation, inheritance in mammal litter sizes in different populations, heritable and molecular genetic variation in mate choice and mating-related genes, osteogenesis imperfecta, tuberous sclerosis complex, and findings in Danon disease, a rare X-linked dominant disorder. |
