Sex differences in gene expression for pupa weight in long term selected lines of Tribolium
Abstract:
Full-sib matings in two populations of Tribolium which had been selected for increased pupa weight for more than 85 generations resulted in a significant inbreeding depression in male progeny but showed no effect in the female progeny. An analysis of variance of a population produced by backcrossing the selected populations to the inbred lines originally used to establish the select populations (Design-III) indicated some genes were still segregating which produce dominance effects in males but not in females. The data support the hypothesis that a class of genes exists, associated with the autosomes, that differ in their dominance effects of pupa weight in the two sexes.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Dosage Compensation
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will have...
