Deviation of Progeny from Population Mean
Mean deviation of progeny from its population mean is known as-
- Transmitting ability — Correct Answer
- Breeding value
- Adaptive value
- None of the above
Explanation:
Correct Answer: Transmitting ability
Transmitting Ability (TA) is defined as the mean deviation of an animal's progeny from the population mean. Since a parent transmits only half its genes to each offspring, TA = ½ × Breeding Value (BV).
Key Genetic Value Definitions
| Term | Definition | Formula |
|---|---|---|
| Transmitting Ability (TA) | Mean deviation of progeny from population mean | TA = BV / 2 |
| Breeding Value (BV) | Twice of transmitting ability; judged by mean of progeny | BV = 2 × TA |
| Phenotypic value (P) | Observed (measured) value of a trait on an individual | P = G + E |
| Genotypic value (G) | Average phenotypic value of all individuals with the same genotype | G = A + D (+ I) |
| MPPA / ERPA | Most Probable Producing Ability / Expected Real Producing Ability — estimates repeatability | Used for culling decisions |
