Sex allocation research has primarily focused on offspring sex‐ratio adjustment by mothers.
Yet, fathers also benefit from producing more of the sex with greater fitness returns. Here, we …

Transmission distorters (TDs) are genetic elements that favor their own transmission to the
detriments of others. Slx/Slxl1 (Sycp3-like-X-linked and Slx-like1) and Sly (Sycp3-like-Y …

Background Goat milk is very similar to human milk in terms of its abundant nutrients and
ease of digestion. To derive greater economic benefit, farmers require more female offspring …

Competition among pollen or sperm (gametic selection) can cause evolution. Mating
systems shape the intensity of gametic selection by determining the competitors involved …

Mendel's law of segregation states that the two alleles at a diploid locus should be
transmitted equally to the progeny. A genetic segregation distortion, also referred to as …

Overexpression of growth hormone (GH) in gh-transgenic zebrafish of a highly studied
lineage F0104 has earlier been reported to cause increased muscle growth. In addition to …

Male germ cells share a common origin across animal species, therefore they likely retain a
conserved genetic program that defines their cellular identity. However, the unique …
