Law of segregation is universally applicable because the gametes

A Are always diploid
B Have only recessive alleles
C Have only dominant alleles
D Are always haploid

Verified Solution

Answer & Solution

Correct Answer

(D) Are always haploid

Step-by-step Solution

Detailed explanation

Since gametes are always haploid Law of segregation is universally applicable, it is the only law without exception. It states that each trait consist of two alleles which segregates during the formation of gametes and one allele from each parent combines during fertilization.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
