sex-linked genes
... The X chromosome carries genes for many traits, while the Y chromosome does not carry these genes. Therefore the phenotype of the females will be determined by the combination of two alleles, while the phenotype of the males will be determined by the allele present on their one X chromosome. ...

In humans, hemophilia is an X
... Genes that are carried on either the X or the Y-chromosome are said to be sex-linked. In humans the small Y-chromosome carries very few genes. The much larger X-chromosome contains a number of genes that are vital to proper growth and development. In fact, it seems to be impossible for humans to dev ...

Sex-Limited, Linked, and Influenced Traits Some traits are carried on

For instance, barred coloring in chickens normally is visible only in the roosters. Sex-linked traits would be considered tra ...
