Accepted Answer

C. Increased regional disparities in agricultural development, particularly between irrigated and rain-fed areas, and a widening gap between large and small farmers. — The Green Revolution, while boosting food production, primarily benefited regions with assured irrigation and larger farmers who could afford the high-yielding variety seeds, fertilizers, and machinery.

Question 7

A couple is seeking genetic counseling due to a family history of an autosomal recessive disorder. The father is identified as a carrier, while the mother has no family history of the disorder and genetic testing confirms she is not a carrier. What is the probability that their child will be affected by this specific autosomal recessive disorder?

Accepted Answer

A. 0% — For an autosomal recessive disorder to manifest, an individual must inherit two copies of the recessive allele (one from each parent). In this scenario, the father is a carrier (Aa) and the mother is not a carrier (AA). Therefore, any child will inherit a dominant 'A' allele from the mother, making it impossible for them to inherit two recessive 'a' alleles and thus be affected by the disorder.
