Which genetic effect is transmitted predictably from a parent to its offspring and forms the main basis of breeding value?
Correct answer: C. Additive gene effect
- A. Epistatic gene effect
- B. Dominance gene effect
- C. Additive gene effect
- D. Environmental effect
Explanation
Additive gene effects are the average effects of individual alleles and are transmitted predictably to progeny. Dominance and epistatic effects depend on particular gene combinations, so they are less reliably passed on.
