Good genes hypothesis | Sexual Selection, Natural Selection ...
good genes hypothesis, in biology, an explanation which suggests that the traits females choose when selecting a mate are honest indicators of the male’s ability to pass on genes that will increase the survival or reproductive success of her offspring.
The Good Genes Hypothesis - SpringerLink
Definition. The good genes hypothesis proposes that the characteristics preferred by females are a signal of males’ ability to pass on genes which will increase the survival and reproductive success of the offspring sired with a male possessing them.

In this work, Darwin fleshed out the mechanism of sexual selection, a hypothesis that he had proposed in The Origin of Species. He went well beyond a simple description of the phenomenon by providing extensive evidence and considering the far-reaching implications of the idea.

Definition. The good genes hypothesis is atheory in evolutionarybiology suggesting that individuals choose mates based on certain traits that indicate genetic quality.
The Good Genes Hypothesis - Springer
The good genes hypothesis (GGH) was formu-lated by evolutionary biologist W.D. Hamilton and behavioral ecologist M. Zuk (1982). It pro-poses that the characteristics preferred by females are a signal of males ability to pass on genes. ’.
Good Genes - SpringerLink
The theory of “good genes” is reinforced by some particularities found in studies of birds and mammals. Among the latter, males mostly do not offer parental care, and therefore it is the indicators of good genes that are decisive for the females’ sexual choice.
6.4: Sexual Selection and Mate Choice - Biology LibreTexts
The GoodGenesHypothesis. The goodgeneshypothesis states that males develop these impressive ornaments to show off their efficient metabolism or their ability to fight disease. Females then choose males with the most impressive traits because it signals their genetic superiority, which they will then pass on to their offspring.
Sexual Selection | Learn Science at Scitable - Nature
Under the ‘goodgenes’ scenario, differences among males provide females with information about the genetic qualities of the different males that can be inherited by the offspring.

A leading hypothesis to answer this question is the goodgeneshypothesis, which is the idea that these sexually-selected, showy male traits are “honest indicators” of good genetic quality. In other words, it takes goodgenes to make a big flashy tail (and to avoid being eaten by a predator, since that big tail slows him down), so the ...

Here, we investigate the effect ofgoodgenes sexual selection on adaptation following environmental change. We show that the strength of sexual selection is often weakened relative to fecundity selection, reducing the suggested benefit of sexual reproduction.
