Answer:
25% heterozygous tall
Explanation:
If we take the F1 generation as parents and let them self-fertilise, we have 4 crosses.
The first one for homozygous tall, then we have 100% AA.
The second and third one for heterozygous tall and we have 25% AA, 50%Aa and 25%aa for each of them.
The last one would be for dwarf, and we'll have 100%aa.
Adding all of them, we'll have
AA = 100 + 25 + 25 = 150%
Aa = 50+50 = 100%
aa = 100 + 25 + 25 = 150%
as we had 4 crosses, so dividing the total percentages by 4, we'll have,
AA = 37.5%
Aa = 25%
aa = 37.5%
:. The percentage of heterozygous tall would be 25%.

The percentage of the F2 progeny of dwarfs is 37.5%.
Self-fertilization is when the fusion of male and female gametes happens within the same plants.
Given,
F1 progeny is 25% similar tall
50% heterozygous tall and 25 % dwarf
To find the % of F2 progeny of dwarf
Adding all the results from the F1 generation
AA = 100 + 25 + 25 = 150%
Aa = 50+50 = 100%
aa = 100 + 25 + 25 = 150%
As we have four crosses, then divide the percentage by 4.
AA = 37.5%
Aa = 25%
aa = 37.5%
Thus, the percentage of F2 progeny of dwarfs is 37.5%
