For example, in some gobies and wrasses, nest sites are limited, and a male's ability to defend his nest depends on body size; individuals tend to start life as females, and only become males once they are sufficiently large to successfully defend a nesting site [48].

Sex Dev 7: 95— For example, if an allele of an autosomal gene is beneficial to males but harmful to females and becomes linked to a dominant masculinizing mutation, then chromosomes that carry both the male-beneficial and male-dominant alleles create a novel Y that can replace the ancestral mechanisms.

However, as we explain below, evidence from a broad array of organisms indicates that the link between sex chromosome heteromorphism and age is often far from direct. With Reverso you can find the English translation, definition or synonym for sex determination and thousands of other words.

The production of sex hormones can result solely from genetics or from genetics in combination with the influence of environmental factors. Charnier published her results in the meeting records of the local Society of Biology in West Africa, a journal with limited distribution, and her efforts were not widely recognized for several years.

In researchers established the existence of genotypic sex determination among turtles , a result that weakened support for TSD in reptiles and in vertebrates.
