Figure 2. These data are consistent with the finding of null Y-linked alleles for all five LG19 markers used to genotype the G. Analysis of the genes located close to these DMCs revealed several genes known to be involved in the response to salinity in fish supplementary data set S5, Supplementary Material online.
The solid black line is the smooth spline fit.

The sex-chromosome diversity that we have uncovered in sticklebacks provides a rich comparative resource for understanding the mechanisms that underlie the rapid turnover of sex-chromosome systems.
When decoding the sequence of a particular gene the recipea cell can manufacture a specific protein.
The X and Y chromosomes have small regions of homology called pseudoautosomal regions. Unlike seed plants, where gametophytes are always unisexual, in bryophytes they may produce male, female, or both types of gamete.
Second occurrence of an X 1 X 2 Y sex chromosome system in Gymnotiformes. Figure S1. Thus, we cannot conclusively determine whether this apparent hypermethylation of chr19 in females is due to differential methylation or from the accumulation of TG polymorphisms on the Y that are being interpreted as unmethylated loci.
Adult threespine stickleback G. These salinities represent the widest range that still allows good fertilization and hatching success in this population supplementary fig.
