What would you expect to happen if your blood sugar was 120mg/100mg? ​
erastova [34]

Answer:

The 120 miligram per 100 milliliter of the sugar suggests that the blood is hyperglycemic.

Explanation:

the hyperglycemia is the condition, in which the blood sugar level increases than the normal blood sugar levels. The main cause of the insulin is decreased function of the insulin hormone. The condition, in which the insulin is not working properly and is unable to metabolise the sugar (glucose) present in the blood is known as Diabetes.

So, the given case can be a result of diabetes.

In the couple described in Problem, the woman gives birth to a color-deficient but otherwise normal daughter. The husband sues f
Rashid [163]

Answer:

See the answer below

Explanation:

<u>From the problem, color is X-linked. Males have just one (XY) chromosome while females have two (XX). Hence, for a recessive trait, males will need only one allele to be affected while females will need two alleles.</u>

Dominant form allele for normal vision = C

Recessive form allele for color deficiency = c

Genotype of a man with normal color vision = X^CY

Genotype of a woman with color deficiency = X^cX^c

Crossing the two:

                                         X^CY    x    X^cX^c

   X^CX^c                       X^CX^c                     X^cY                    X^cY

<em>normal female     normal female      affected male      affected male</em>

(a) All their sons would be affected for color deficiency. Hence, the probability of them having a color-deficient son is 100% or 1.

(b) None of their daughters is supposed to be affected for color deficiency. Hence the probability of them having a color-deficient daughter is 0.

<em>If the woman gives birth to a color-deficient but otherwise normal daughter and husband sues for a divorce on the ground of adultery, the case will definitely stand up in the court because none of their daughters can be affected for color deficiency based on genes of the man and the woman. </em>

<em>In order to produce an affected daughter, the father will need to supply an affected X chromosome in conjunction with the one that will be supplied by the woman. </em>

<em>In this case, the man does not have an affected chromosome, hence it is not possible for them to have an affected daughter except that the woman slept with another man who happens to have an affected X chromosome.</em>
