Answer:
This disorder is caused by a recessive allele, its inheritance is sex-linked.
Explanation:
The disorder affects boys born to unaffected parents, this means that at least one of them has to be a carrier of the allele which causes the disease. So, if the allele was dominant, it would express in parents and sons. But, in this case, only is expressed in sons, so it can´t be dominant. Moreover, this condition has a sex-linked inheritance because it is always seen in boys and never in girls. This happens due to boys only have an X chromosome, so if they inherit the recessive allele of the disease, they will express it. On the other hand, girls have two X chromosomes, so if they inherit one copy of the recessive allele, they will be carriers and they won't be affected.
This disorder is never seen in females because they need to have two copies of the recessive allele. However, to have double copy, they should inherit one copy from their mothers and one copy of their fathers, but boys with the allele are affected and they die in early teens without having progeny. Therefore, a girl can't have a "carrier-father", so they will never have two copies to express the disorder.

Answer:
Cancer is formed when there are mutations in a number of genes.
Explanation:
Malignant tumors are gene diseases which do not mean that cancer is necessarily an inherited disease (only in 5-10% of cases the cancer is inherited) because the vast majority of other tumors are the result of somatic, ie secondary, mutations that lead to malignant transformation.
Only 2% of human diseases are monogenic (caused by a change in one gene). The remaining 98% of the disease is either polygenic (caused by a change in several genes at the same time) or epigenetic (caused by non-genetic or post-genetic disorders of cellular molecules).

The correct answer choice which best describes the purpose of the cell cycle for skin cells in this circumstance is <u>reproduction</u>
The correct answer choice is a
<h3>Healthcare </h3>
Healthcare can simply be defined as an organized medical care given to a person, organization or even a community either by a doctor, nurse or any other licensed healthcare professional
However, healthcare-associated Infections, are those infections patients can get during their treatment for another condition due to bacteria, viruses, fungi, and other pathogens.
And for a good reason, the fundamental purpose of healthcare is to enhance healthy living and quality of life by giving quality healthcare services.
So therefore, the correct answer choice which best describes the purpose of the cell cycle for skin cells in this circumstance is reproduction
