Detailed Solution for Test: Genetics - 2 - Question 3

To determine the proportion of dwarf progeny, let's analyze the cross between a heterozygous tall plant (Tt) and a homozygous dwarf plant (tt).
Genotype of tall plant: Tt
Genotype of dwarf plant: tt
When these two plants are crossed, the possible genotypes of the progeny are as follows:
1. Tt (tall)
2. Tt (tall)
3. tt (dwarf)
4. tt (dwarf)
From these genotypes, we can see that 2 out of 4 possible genotypes (50%) will result in dwarf progeny.
Therefore, the proportion of dwarf progeny is 50% (option A).
