Runaway selection involves positive feedback between:

Male trait and female preference reflects key principle in quiz on sexual selection + pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Male trait and female preference 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 Male trait and female preference fits helps integrate natural selection, drift and species concepts essential for NEET, CSIR-NET and GATE examinations

Runaway sexual selection was proposed by:

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 Fisher describes process enhancing reproductive rather than viability fitness. This concept integrates genetics, ecology and
