Given the importance of small offshore islands as refuges, both natural and artificial, for many Australian species Eldridge et al. Within Kangaroo Island, we detected no difference in the mean inbreeding coefficient between males and females, but we observed that mean relatedness was significantly higher among females than among males.
Greater genetic diversity at autosomal loci in the earlier studies may therefore reflect greater heterogeneity in sampling locations. Greater relatedness among females than males provides evidence for male-biased dispersal in this population, while sex-linked markers identified genetic lineages not apparent from autosomal data alone.
Future work may indicate circumstances where it is appropriate to consider extension of current management practices to specifically monitor genetic variation at sex chromosome markers and to non example of sex linked genes in Esperance threatened populations through sex-specific translocations, for example, to increase Y chromosome diversity within isolated island populations.
Sex-linked inheritance and autosomal inheritance are two types of inheritance patterns. In the first cross left all of the offspring have red eyes. So what's also very interesting is that you can imagine that for individuals who are XY or males, having these different mutations on the genes, on the X chromosome, is particularly problematic, because unlike females, there are not two X chromosomes that give you the potential of carrying a normal gene on the X chromosome.
Therefore, every cell non example of sex linked genes in Esperance forms from a particular embryonic cell has the same X chromosome inactivated. Male sperm cells may carry one of two types of sex chromosomes. However, studying sex-linked inheritance is easy than studying autosomal inheritance.
