Genotype-by-sex interactions occur when the effect of genotype on expression differs between males and females. In Drosophila, sex determination is achieved by a balance of female determinants on the X chromosome and male determinants on the autosomes.
Sunderland MA : Sinauer Associates ; By leveraging a recent, large genetic study of gene expression Battle et al.

When the value of the autosomes exceed the sex chromosomes, the organism is a male, while when the value of autosomes is lesser, then the organism is a female.
The females produce ova all of one type having X chromosome. The genes present on autosomes are responsible for determining the somatic characters but chromosomal theory of sex determination ppt in Montreal influence the sex of the organism.
Differences in chromatin accessibility are well known to influence gene expression and the exposure of genetic variants Thurman et al. Figure 2. J Transl Med 6 : Again, if the normality assumption for the regression residuals was not rejected, we tested for differences between males and females in regression residual expression variance using either an F -test or a Brown-Forsythe Levene-type test.
Transcriptome and genome sequencing uncovers functional variation in humans.
Although both mammals and fruit flies produce XX females and XY males, their chromosomes achieve these ends using very different means. In humans, hermaphrodes are rare and usually sterile. To ensure that this depletion of eQTLs on the X Chromosome was not due to lower power in the X Chromosome compared to the autosomes, e.
The differential activation of the sxl gene in females and males.
