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.
The scientific method is something you probably use in your life more often than you realize, often without even thinking of it.

What is role of science in daily life?</h3>
Science has day to day contribution in our life. It is involved in breathing, exhaling, brushing of teeth, cooking, bathing etc. It developed the standard of livings.
Fasting is the very beneficial health practice followed from ancient times.In india, it is also consider as relegious practice from ancient times and they scientifically proved good for health.
I will choose fasting as it improve overall fitness, blood sugar management, improve immunity and detoxify the body.By doing so, my health get improved and my body get detoxify naturally.

<span>i think that disease would have greatest impact in :
Tendons and cartilage tendons
tendons and cartilage tendons connect, support, and bind other tissue organ with the colagen that they contained with.
This is where the word "connective" tissue came from</span>
Some organisms that reproduce asexually are hydra, bacteria, and single celled organisms. Meiosis is the production of sperm<span> and egg cells. These cells are "Gamete" or "Sex" cells.

The right answer is B and C.
For proposal C, I will give you an example, that of an autosomal recessive disease. If a parent is heterozygous for an allele causing an autosomal recessive disease (due to a mutation), it may be that it transmits the allele to its descendence, as it may not be able to transmit it (since in one heterozygous subject, not all of its gametes carry the mutated allele) and thus the mutation will no longer be copied through the generaitons.
Each individual is genetically unique. Its genes are distributed along chromosomes contained in the nucleus. Mutations can lead to the appearance of different versions of genes: alleles. A diploid individual has two copies of each gene, which may be identical or different alleles. Mixing during sexual reproduction partly explains the genetic diversity of individuals.
