dosage compensation — Genetic mechanisms that allow genes to be expressed at a similar level irrespective of the number of copies at which they are present. Usually invoked for genes that lie on sex chromosomes, that are thus present in different copy numbers in males … Dictionary of molecular biology
dosage compensation — A regulatory mechanism for sex linked genes, to allow equivalent levels of gene expression from (in mammals) XY or XX genotypes, even though the gene copy number in XX is double that in XY. See: sex linkage, Barr body … Glossary of Biotechnology
dosage compensation — noun : the genetic mechanism by which the same effect on the phenotype is produced by a pair of identical sex linked genes in the sex (as the human female) having the two sex chromosomes of the same type as by a single sex linked gene in the sex… … Useful english dictionary
