Dosage compensation in birds appears to be phenotypically and molecularly quite different from X inactivation, being partial and gene-specific, but both systems use tools from the same molecular toolbox and there are some signs that galliform birds represent an early stage in the evolution of a coordinated system.
Two major types of chromosomes can be found in eukaryotic cells. Sex Chromosomes: A few somatic sex chromosomes in La Trobe the chromosomes within a genome are sex chromosomes. The effects of genes carried only on the Y chromosome are, of course, expressed only in males.
In humans the sex chromosomes consist of one pair of the total of 23 pairs of chromosomes. The joining of two gametes containing both X chromosomes produces a female offspring. Autosomes: Autosomes are labeled with numbers, from 1 to
The bird W and mammal Y have both undergone extensive degradation, but some birds retain early stages and some mammals terminal stages of the process, suggesting that the process is more advanced in mammals.
