The discovery of the Sry gene in 1990 triggered a revolution in our understanding of sex
determination. More recently, advances in non-model organisms have been fuelled by the …

Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex
chromosome systems, making it possible to empirically test the rich body of evolutionary …

Female Aedes aegypti mosquitoes infect more than 400 million people each year with
dangerous viral pathogens including dengue, yellow fever, Zika and chikungunya. Progress …

Background Capturing the genetic diversity of wild relatives is crucial for improving crops
because wild species are valuable sources of agronomic traits that are essential to enhance …

Apomixis, the clonal formation of seeds, is a rare yet widely distributed trait in flowering
plants. We have isolated the PARTHENOGENESIS (PAR) gene from apomictic dandelion …

We gathered genomic data from grapes (Vitis vinifera ssp. vinifera), a clonally propagated
perennial crop, to address three ongoing mysteries about plant domestication. The first is the …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Current theory proposes that degenerated sex chromosomes—such as the mammalian Y—
evolve through three steps:(i) recombination arrest, linking male-beneficial alleles to the Y …

The effective size of a population, N e, determines the rate of change in the composition of a
population caused by genetic drift, which is the random sampling of genetic variants in a …

Among dioecious flowering plants, females and males often differ in a range of
morphological, physiological, and life-history traits. This is referred to as sexual dimorphism …
