Sexual selection

Overall reproductive success depends on balance between:

Always increases survival reflects key principle in quiz on sexual selection + pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Always increases survival aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why Always increases survival fits helps integrate natural selection,

Sexual selection

Sexual selection can oppose:

Sexual selection, proposed by Darwin in 1871, favors traits increasing mating success rather than survival, via intrasexual competition among same sex and intersexual choice where choosier sex, often females investing more in gametes, selects mates. It explains elaborate ornaments, good genes indicators like MHC diversity and parasite resistance per Hamilton-Zuk hypothesis. Fisherian runaway and handicap principles describe coevolution of preference and trait. Therefore Natural selection describes process enhancing reproductive rather than viability fitness. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.

Sexual selection

Sexual selection differs from natural selection because it focuses on:

Sexual selection, proposed by Darwin in 1871, favors traits increasing mating success rather than survival, via intrasexual competition among same sex and intersexual choice where choosier sex, often females investing more in gametes, selects mates. It explains elaborate ornaments, good genes indicators like MHC diversity and parasite resistance per Hamilton-Zuk hypothesis. Fisherian runaway and handicap principles describe coevolution of preference and trait. Therefore Reproduction describes process enhancing reproductive rather than viability fitness.
