They are said to be linked because more males XY develop these triats than females XX. Get your answers by asking now. What is the different between inherited traits and learned traits? They are traits that their genes are carried on autosomes and the sex of individual acts to modify their dominance where the act of these genes is influenced by the hormones secreted from gonads of adult males and femalesSometimes, the sex of living organism acts to modify the dominance of some traits that are called sex-influenced traits, such as the presence of horns in cattle trait and genetic baldness trait in humans.
Sexlinked traits are alleles that reside on the X or Y chromosomes but generallly refer to alleles on the X chromosome that do not have a matching allele on the Y chromosome. Sex linked is general term both for X linked and Y linked traits.

As reported previously for mice from the core cross on an outbred genetic background De Vries et al. As shown in the table, the offspring of this cross exhibited a ratio of red eyes to white eyes, which indicated that white eyes were recessive.
However, there was no contribution of sex chromosome complement, nor was an interaction detected Table 3. Morgan 's resistance to the chromosome theory. An examination of the proportion of mice that displayed aggression on the first encounter with an intruder i.
