| (a) Dominance | (i) Many genes govern a single character |
| (b) Codominance | (ii) In a heterozygous organism, only one allele expresses itself |
| (c) Pleiotropy | (iii) In a heterozygous organism, both alleles express themselves fully |
| (d) Polygenic inheritance | (iv) A single gene influences many characters |
Options
- Aa - ii; b - i; c - iv; d - iii
- Ba - ii; b - iii; c - iv; d - i
- Ca - iv; b - i; c - ii; d - iii
- Da - iv; b - iii; c - i; d - ii
Correct answer
B. a - ii; b - iii; c - iv; d - i
Step-by-step solution
Dominance- In a heterozygous organism, only one allele expresses itself.
Codominance- In a heterozygous organism, both alleles express themselves equally.
Pleiotropy- A single gene influences many characters.
Polygenic Inheritance- Many genes govern a single character.
Codominance- In a heterozygous organism, both alleles express themselves equally.
Pleiotropy- A single gene influences many characters.
Polygenic Inheritance- Many genes govern a single character.
