The illustration above is a genetic diagram. Study it and answer the question below
What do the labels I, II, III, and IV respectively represent?
- Ee, Ee, EE and E
-
EE, EE, Ee, and Ee
- EE, EE, EE and EE
- EE, EE, Ee and ee
The correct answer is: B
Explanation
The labels I, II, III and IV represent the genotypes of the offspring from a cross between two heterozygous parents (Ee). I and II represent the homozygous dominant (EE) and heterozygous (Ee) offspring, respectively, while III and IV represent the heterozygous (Ee) and homozygous recessive (ee) offspring, respectively.
