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

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.
