However, for males, there only needs to be one copy of an X-linked recessive gene in order for the trait or disorder to be expressed. For example, a woman can carry a recessive gene on one of the X chromosomes unknowingly, and pass it on to a son, who will express the trait:Therefore, half of the daughters have the gene and can pass it to the next generation.The other half do not have the gene and, therefore, cannot pass it on.owever, for males, there only needs to be one copy of an X-linked recessive gene in order for the trait or disorder to be expressed.

These proteins are formed as a result of genes carried on chromosomes. In genetics genes are represented by letters. There are usually 2 different types of the same gene; one is dominant and one is recessive. An example of this is: T is a gene for tall and t is a gene for short. The two versions of the same gene are called alleles. The two alleles are formed at the same position, or locus, on the chromosome.
