Question

according to the good genes hypothesis, variation in male traits provide females with information about the genetic qualities of the different males that can be inherited by the offspring. which of the following outcomes, on its own, would provide support for the good genes hypothesis? select all that apply:
the ornamentation of one sex is correlated with offspring fecundity.
one sex chooses another sex for mating based on ornamentation.
in one sex, individuals who mate are stronger than their competition.
the ornamentation of one sex is correlated with its offsprings ability to resist disease.

Explanation:

• The good genes hypothesis focuses on how traits (like ornamentation) can indicate genetic quality that benefits offspring.
• If ornamentation is correlated with offspring fecundity (ability to reproduce), it shows the trait (ornamentation) is linked to a beneficial genetic - related outcome (more offspring), supporting the hypothesis.
• If ornamentation is correlated with offspring's disease - resistance (a genetic - based quality), it also supports the idea that ornamentation indicates good genes.
• Just choosing a mate based on ornamentation (without a link to offspring quality) doesn't directly support the good genes hypothesis as it could be for non - genetic - quality reasons (like random preference).
• One sex having stronger mating individuals (without a link to offspring quality) also doesn't directly support the good genes hypothesis as strength could be due to non - genetic factors (like environmental) or not related to offspring genetics.

Answer:

• The ornamentation of one sex is correlated with offspring fecundity.
• The ornamentation of one sex is correlated with its offspring's ability to resist disease.
