What phenomenon can result in offspring that produce a higher yield than their true-breeding parents?
What phenomenon can result in offspring that produce a higher yield than their true-breeding parents?
- Complete dominance
- Sex-limited trait
- Multiple alleles
- Epistasis (correct)
How is epistasis different from complete dominance?
How is epistasis different from complete dominance?
- Epistasis involves interactions between alleles of the same gene, while complete dominance involves interactions between alleles of different genes.
- Epistasis only occurs in dihybrid crosses, while complete dominance can occur in any type of genetic cross.
- Epistasis results in the expression of one gene masking the expression of another, while complete dominance does not involve masking.
- Epistasis involves interactions between alleles of different genes, while complete dominance involves interactions between alleles of the same gene. (correct)
