Match List - I with List - II.
| List - I | List - II |
|---|---|
| (A) Human skin colour | (I) Multiple allelism |
| (B) Pair of alleles expressing contrasting traits | (II) Polygenic inheritance |
| (C) ABO blood group | (III) Incomplete dominance |
| (D) Antirrhinum flower colour | (IV) Heterozygous |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
(A) Human skin colour — this matches (II) Polygenic inheritance. Three or more genes act together, and each allele adds to the colour.
(B) Pair of alleles expressing contrasting traits — this matches (IV) Heterozygous. A heterozygote carries two different alleles of a gene, such as Tt.
(C) ABO blood group — this matches (I) Multiple allelism. The gene I has three alleles (IA, IB, i) in the population.
(D) Antirrhinum flower colour — this matches (III) Incomplete dominance. Red × white gives pink F1 in snapdragon.
