The relationship between sexual dimorphism and intersex correlation: do models support intuition?

Genetics - 12 Nov 2025

Puixeu Gemma, Hayward Laura Katherine

Abstract excerpt

The evolution of sexual dimorphism (SD) (the difference in average trait values between females and males) is often thought to be constrained by shared genetic architecture between the sexes. Indeed, it is commonly expected that SD should negatively correlate with the intersex correlation (the genetic correlation between effects of segregating variants in females and males, rfm), either because (1) traits with...
