Y chromosome markers in M. annua
Confirmation of male-specific PCR markers in the annual plant Mercurialis annua.
Simulations of transitions between genetic and non-genetic sex determination
Incomplete penetrance of sex determination in frogs, and achiasmatic meiosis in males, allows for interesting possibilities in the evolution of a new sex chromosome.
Characterisation of YY plants in M. annua
A study of viability and fertility of YY plants, produced by hormonal treatment and prunning, allows to determine the phenotypic effects of possible Y chromosome degeneration.
Comparison of mating success between XX and XY males
Variation in the extent of sex chromosome differentiation exists within the same population for the common frog, Rana temporaria. This alows to directly compare possible effects on male fitness while controlling for the rest of the genome, and the environment.
Gene expression comparison between XX and XY males
RNAseq analysis of males and females from a population with varying degrees of genetic differentiation between the X and the Y chromosomes.
Genetic differentiation analysis using haploid embryos
Sequencing of only the Y chromosome is possible through the generation of haploid embryos in frogs.
