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
توضیح
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.
