Researchers hypothesized that cocaine is pharmacologically active in primate fetal brain when pregnant primates are administered

pav-90 [236]

Answer:

Option A, Glucose metabolism in the fetal brain increased

Explanation:

Usage of cocaine during pregnancy is prohibited. However, in case if cocaine is taken it disrupts the metabolism as it increases brain glucose metabolism to the level of an adult human being. Since glucose metabolism in brain is a sensitive process, any disruption in it can lead to unaccounted effects such as dysfunctional circulation, and pharmacological effect. Cocaine increases the dopamine by blocking the dopamine transporters thereby increasing the Vmax. Since the brain of a child has all kind of neurochemical components, cocaine intakes by a pregnant woman produces reinforcing effects in brain of fetus and also make it pharmacologically active

Hence, option A is correct

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is inherited as an X-linked recessive allele in humans. A woman whose father

prohojiy [21]

Answer:

(a) 1/2; (b) no

Explanation:

Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.

In contrast to this, her husband is diseased so his genotype will be XᵇY.

The Punnett square diagram related to the cross is attached.

(a) Proportion of their sons expected to be G6PD is 1/2:

They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.

(b) If the husband were G6PD deficient, the answer will not change.

The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.
