Answer:

For this type of inheritance, females can pass down diseased alleles to offspring through TWO X chromosomes, while males can pass down alleles through ONE X chromosome

Explanation:

This is indicative of the X-Linked inheritance.

It's important to note that Sex-linked alleles possesses a unique process of inheritance when viewed against those on autosomal chromosomes due to the X chromosome bearing the allele and not the Y chromosome. It suggests why men have an higher chance of carrying a sex-linked diseases, as their only allele stored on their one X chromosome is expressed.

The male and female are differs in their X-linked attributes. The genes located on the X chromosomes have seperate ways of expression in males and females which is as a result of the female having two X chromosomes and the males having only one. (Hemizygous for X-linked traits).

The X-linked recessive is the inheritance of a recessive allele at the X-chromosome. It is well expressed in males than females as males only have to inherit a defective X-chromosome (dominant/recessive) from the mother while the female with just one recessive X-chromosome does not show the disease phenotype since two defective recessive alleles is needed for them to be influenced by the disease.

Therefore, in the aspect of X-linked diseases, females functions as carriers and males are majorly impacted since the males would normally inherit the mother's X-chromosome.
