17,19,20. Nature has evolved numerous variations to this generally accepted theory of sex chromosome evolution and sex determination. For example, neo-sex chromosomes can also evolve in situations where a sex chromosome pair already exists, either by fusion to an autosome or by acquisition of a ...

Theory predicts that sex chromsome linkage should reduce intersexual genetic correlations thereby allowing the evolution of sexual dimorphism. Empirical evidence for sex linkage has come largely from crosses and few studies have examined how sexual dimorphism and sex linkage are related within outbred pop...
Early on (Matthey, 1945) it was suggested that the diploid chromosome number of different mammals is less useful for the evaluation of karyological evolutionary theory than the total number of chromosome arms. This number of chromosome arms is called the fundamental number and is generally more uni...

The severity of the mental defect and the testicular changes may be proportional to the number of supernumerary X chromosomes, as suggested by others, but a review of literature shows that statistical proof for this theory is lacking. The clinical significance of an extra Y chromosome remains ...
