14. However, excluding insects, around one-third of animal species are hermaphroditic15, and transitions to gonochorism have occurred within flatworms,

Before turning to the genomic and molecular underpinnings of how the sexes may break the genetic correlation, we will discuss the complexity that necessarily accompanies evolution of POLS—genetic covariances between traits. Sexual dimorphism in POLS traits evolves largely as a result of sex-specific s...
From an evolutionary perspective, the filariae represent an interesting contrast to the model nematodeC. elegans, which has, like many other nematodes, XX/XO sex determinism, while filarial species can have Y chromosomes8,9,10,11,12,13,14,15. It is generally held that evolution of heteromorph...
A variety of approaches have been used to understand the evolution of male parental care. General frameworks are provided by Trivers’ theory of sexual selection (1972), the theory of life history strategies (see Horn, 1978; Stearns, 1976) and game theor
We further confirmed this chromosomal rearrangement using dual-color fluorescence in situ hybridization (FISH) with two bacterial artificial chromosome (BAC) clones of the Indian muntjac (Muntiacus muntjac vaginalis) as probes (Figure 1b). The green signal in the middle of X+4 has switched its ...

(i.e., the community of species in which an interaction takes place). Thus the presence or absence of tertiary species can lead to the formation of selection mosaics, such as described in crossbill–lodgepole–squirrel example given previously (Benkman, 1999). Actually, measuring G × G ×...
