Alkaptonuria is an infrequent autosomal recessive condition. It is first noticed in newborns when the urine in their diapers tur
Arisa [49]

Answer:

See the answer below

Explanation:

Let the disorder be represented by the allele a.

Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.

Since the four adults are carriers, their genotypes would be Aa.

                    Aa     x     Aa

Progeny:    AA    2Aa    aa

Probability of being affected = 1/4

Probability of being a carrier = 1/2

Probability of not being affected = 3/4

(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2

(b) The chance that  the third child of Sara and James will be free of the condition = 3/4

(c)

(d) If someone has no family history of the disorder, their genotype would be AA.

                 AA     x     aa

                        4 Aa

<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0

(e)

(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0

Polycystic ovary syndrome is an endocrine disorder and a common cause of chronic anovulation. In addition to the clinical manife
Scilla [17]

Answer:

1. Insulin resistance and diabetes

2. Metformin

Explanation:

Metformin can be used to treat polycystic ovary syndrome, especially for insulin-resistant women (insulin is a hormone that transports sugar into cells).

People with insulin resistance have high levels of this hormone in their blood and excess circulating insulin can aggravate manifestations of polycystic ovary syndrome, and also increase the risk of diabetes.

The main benefits of metformin in the treatment of polycystic ovaries is the normalization of menstrual irregularity and the restoration of ovulatory cycles.

Since most women with polycystic ovary syndrome are insulin resistant, metformin is a good treatment option in some cases.

However, the treatment of polycystic ovary syndrome should be individualized for each woman, depending on the symptoms presented and the goal to be achieved with the treatment.
