Duchenne muscular dystrophy is an X-linked recessive disease. A phenotypically normal couple wants to start a family. The woman’

Andreyy89

Answer:

$\frac{1}{8}$

Explanation:

From the question: Duchenne muscular dystrophy is an X-linked recessive disease.

Now for an X-linked recessive disorder to be affected by a male individual; it only requires the presence of only one copy of the recessive allele of the disease to be present BUT in a female individual. both copies of the recessive allele must be present.

Let the X-linked recessive disease(i.e Duchenne muscular dystrophy) be = (ⁿ)

However, we are told that the couples are normal and are unaffected. Therefore;

the male partner (XY) will be: $X^NY$

the female partner (XY) will be: $X^NX^N$

Similarly, the question proceeds by telling us that: the woman's brother has the disease.

Definitely, it's possible that this unaffected woman is a carrier of the disease.

So, if she is a carrier; we have her traits to be: $X^NX^n$

NOW, if a cross exist between these couples; we have

$X^NY$ × $X^NX^n$

$X^N$ $Y$

$X^N$ $X^NX^N$ $X^NY$

$X^n$ $X^NX^n$ $X^nY$

So, we have offspring as follows:

$X^NX^N$ = normal unaffected female

$X^NY$ = normal unaffected male

$X^NX^n$ = female carrier for the Duchenne muscular dystrophy disease

$X^nY$ = affected male with the Duchenne muscular dystrophy disease

So, the probability of the child to be affected with the disease = $\frac{1}{4}$

Also, the probability that the first child will be a male or a female = $\frac{1}{2}$

∴

the probability that the couple’s first child will be affected = $\frac{1}{4}*\frac{1}{2}$

= $\frac{1}{8}$

Which layer of the alimentary canal contains not only glands and blood vessels but also a nerve plexus that helps regulate diges

Galina-37 [17]

Answer: The external submucosa I'd the layer of the alimentary canal that contain the blood vessels,glands and nerve plexus that help to regulate digestive activity.

Explanation:

The alimentary canal or gastrointestinal tracts is the organ in the body that helps to break down ingested food into pieces that can be absorbed by human body and expels unwanted food as wastes. The alimentary canal consists of structures from mouth to the anus. The alimentary canal have four distints layers which are the the mucosa, submucosa,muscular layer and serosa.

The mucosa is the inner layer of alimentary canal and it surrounds the lumen. This layer have direct contact with digested food.

The submucosa consists of dense connective tissues, blood vessers, glands and nerve plexus. It regulate digestive activity.

The muscular layer consists of inner circular layer and longitudinal circular layer. It prevents food from going backward.

The serosa is the external layer of the alimentary canal and iits have several connective tissues.
