The Hardy-Weinberg equation p^2 + 2pq + q^2 = 1 is used to calculate: MCQ with Answer and Explanation

The Hardy-Weinberg equation p^2 + 2pq + q^2 = 1 is used to calculate:
A. The rate of mutation in a population
B. The carrying capacity of an ecosystem
C. The energy transfer between trophic levels
D. The expected genotype frequencies in a population
Answer: Option D
Solution (By JKSSB Mock Tests)
The Hardy-Weinberg equation is a fundamental principle in population genetics used to calculate the expected frequencies of genotypes in a population that is not evolving (in genetic equilibrium). 'p' represents the frequency of the dominant allele, and 'q' represents the frequency of the recessive allele. p^2 is the frequency of the homozygous dominant genotype, 2pq is the heterozygous genotype, and q^2 is the homozygous recessive genotype.

Question #1
The structure that prevents the backflow of urine from the bladder to the ureters is the:
A. Ureterovesical valve
B. Detrusor muscle
C. Renal pelvis
D. Urethral sphincter

Correct Answer: Option A


Explanation:
The oblique entry of the ureters into the bladder creates a valve-like effect, preventing reflux. The urethral sphincter controls urination.

Question #2
In human digestive system, the enzyme that digests fats is:
A. Lipase
B. Sucrase
C. Amylase
D. Pepsin

Correct Answer: Option A


Explanation:
Lipase is the fat-digesting enzyme, produced mainly by the pancreas (pancreatic lipase) and also by lingual and gastric glands. It hydrolyzes triglycerides into monoglycerides and free fatty acids. Bile salts emulsify fats, increasing surface area for lipase action. Amylase digests starch, pepsin digests proteins, sucrase hydrolyzes sucrose. Lipase requires colipase for optimal activity.

Question #3
The part of the seed that emerges first during germination and develops into the root is the:
A. Radicle
B. Plumule
C. Hypocotyl
D. Cotyledon

Correct Answer: Option A


Explanation:
The radicle is the embryonic root, and it is the first structure to emerge from the seed coat during germination, growing downward to anchor the plant and absorb water. The plumule becomes the shoot, hypocotyl connects radicle to cotyledons, cotyledons are seed leaves.
