The illustration above is a genetic diagram. Study it and answer the question
What is the genotypic ratio
-
1:1
- 4:0
- 1:3
- 1:2:1
The correct answer is: A
Explanation
The genotypic ratio is the ratio of the number of individuals with different genotypes. From the diagram, if you do the crossing I = EE, II = EE, III = Ee, IV = Ee i.e 2 EE and 2 Ee
⇒ Genotypic ratio will be 2 : 2 which is equivalent to 1:1.
