Match the terms in Column I with their description in Column II and choose the correct option.
| Column I | Column II | |---|---| | (A) Dominance | (p) Many genes govern a single character | | (B) Codominance | (q) In a heterozygous organism only one allele expresses itself | | (C) Pleiotropy | (r) In a heterozygous organism both alleles express themselves fully | | (D) Polygenic inheritance | (s) A single gene influences many characters |
Solution
Dominance (A) means that in a heterozygote, only one allele (the dominant one) expresses itself phenotypically, masking the other — matching (q). Codominance (B) means both alleles of a heterozygote express themselves fully and independently — matching (r). Pleiotropy (C) is the
