easy · MCAT bio-biochem
A researcher is studying two genes that are located very close to each other on the same chromosome. They notice that the offspring of a dihybrid cross do not follow the expected 9:3:3:1 phenotypic ratio. This phenomenon is known as:
- Codominance
- Pleiotropy
- Genetic linkage
- Epistasis
