Ability to Stamp Characters on Progeny
Ability of an individual to stamp its characters on its progeny is known as-
- Prepotency — Correct Answer
- Penetrance
- Expressivity
- Panmixia
Explanation:
Correct Answer: Prepotency
Prepotency is the ability of an animal (especially a highly homozygous/inbred sire) to consistently transmit its own characteristics to offspring, making them resemble that parent more strongly and uniformly than the other parent.
Key Genetic Terms — Comparison
| Term | Definition | Example |
|---|---|---|
| Prepotency | Ability of an individual to stamp its characters uniformly on progeny; increased by inbreeding/homozygosity | A prepotent Hereford bull produces consistently uniform, Hereford-type calves regardless of the dam breed |
| Penetrance | Percentage of individuals with a given genotype that actually express the corresponding phenotype | 100% penetrance = all individuals with genotype express the trait |
| Expressivity | Degree or extent to which a given genotype is expressed phenotypically | Variable expressivity = same genotype produces different phenotype intensities |
| Panmixia | Random mating within a population | Key assumption of Hardy-Weinberg equilibrium |
