The incidence of the various genotypes in a population showing a sex-linked recessive character

Genetica Aims and scope Submit manuscript

Summary

Although the inheritance of a sex-linked recessive trait is well known, not all consequences are sufficiently realised. Therefore, the facts are presented once more in a new form.

All populations that are unaffected by selection tend to stabilisation. When this has been reached the five different genotypes are bound by definite and rather simple numerical relations. Whereas the percentages of normal (X-) and affected (x-) males, and also those of homozygous normal (XX) and affected (xx) females may vary between 0 and 100, the percentage of heterozygous females (Xx) in a stable population never exceeds 50%.
