Genes of Testis-determining factor (TDF) and hypertrichosis are present on the Y-chromosome. Inheritance of these characters is only through the male. Such characters are known as:
Genes of sex-limited traits are present on:
Genes of sex-influenced traits are present on:
Genes of sex-linked traits are present on:

The product of realized heritability and selection differential is known as:
The ratio of selection differential to the phenotypic standard deviation of a trait is known as:
