Gene dosage is the number of copies of a particular gene present in a genome. [1] Gene dosage is related to the amount of gene product (proteins or functional RNAs) the cell is able to express. Since a gene acts as a template, the number of templates in the cell contributes to the amount of gene product able to be produced.
Hormone levels with 2 mg oral micronized estradiol valerate tablets (Progynova, Schering) taken 3 or 4 times per day (6–8 mg/day total) sublingually (SL) in premenopausal women. [6] [7] Time of blood collection after medication administration was not specified. [6] [7] Sources: Serhal et al. (1989, 1990). [6] [7]
Z-specific genes were over-expressed in males when compared to females, and a few genes had equal expression in both male and female Z chromosomes. [citation needed] In chickens, most of the dosage compensated genes exist on the Zp, or short, arm of the chromosome while the non-compensated genes are on the Zq, or long, arm of the chromosome.
More women may benefit from gene testing for hereditary breast or ovarian cancer, especially if they've already survived cancer once, an influential health group recommended Tuesday. At issue are ...
Thomas Johnson later showed that life extension of up to 65% was due to the mutation itself rather than due to calorie restriction, [2] and he named the gene age-1 in the expectation that other genes that control aging would be found. The age-1 gene encodes the catalytic subunit of class-I phosphatidylinositol 3-kinase (PI3K).

Theoretically, X-inactivation should eliminate the differences in gene dosage between affected individuals and individuals with a typical chromosome complement. In affected individuals, however, X-inactivation is incomplete and the dosage of these non-silenced genes will differ as they escape X-inactivation, similar to an autosomal aneuploidy.
