A reciprocal cross is especially useful for detecting whether inheritance of a trait is influenced by:
Correct answer: A. Maternal or sex-linked effects
- A. Maternal or sex-linked effects
- B. Only additive gene action
- C. Only environmental temperature
- D. The number of autosomes alone
Explanation
In reciprocal crosses, the parental sexes are reversed. Different results between the two crosses may indicate sex-linked inheritance, maternal effects, or cytoplasmic inheritance rather than purely autosomal inheritance.
