Genetic Background
In this plant genetics scenario, we have:
- Red fruit (R) is dominant over yellow fruit (r).
- Tallness (T) is dominant over shortness (t).
The genotype of the plants involved in the cross is as follows:
- Parent 1: T_R_ (dominant for both traits)
- Parent 2: rrtt (homozygous recessive for both traits)
Understanding the Cross
To determine the genotype of Parent 1, we know it has at least one R and one T allele, but the exact genotype for the tall plant (T_R_) needs to be defined. Since we are crossing this with a homozygous recessive plant (rrtt), let's assume Parent 1 is heterozygous:
- Parent 1: RrTt
- Parent 2: rrtt
Possible Gametes
From the genotypes, we can identify the possible gametes produced by each parent:
- Parent 1 (RrTt) can produce: RT, Rt, rT, rt
- Parent 2 (rrtt) can produce: rt (only one type)
Progeny Genotypes
When we perform the cross:
- Combine each gamete from Parent 1 with the gamete from Parent 2 (rt):
- RT (Red, Tall)
- Rt (Red, Short)
- rT (Yellow, Tall)
- rt (Yellow, Short)
However, since Parent 2 is rrtt, we only consider RT and Rt combinations. Thus, the resulting progeny will be:
- 50% Red, Tall (RrTt)
- 50% Red, Short (Rrtt)
Conclusion
Thus, the correct interpretation of the progeny is:
- All will have red fruits (due to the R allele).
- 50% will be tall (RrTt) and 50% will be short (Rrtt).
Hence, the correct answer is option 'B': All red fruit, tall 50%.
In this plant genetics scenario, we have:
- Red fruit (R) is dominant over yellow fruit (r).
- Tallness (T) is dominant over shortness (t).
The genotype of the plants involved in the cross is as follows:

- 50% will be tall (RrTt) and 50% will be short (Rrtt).
Hence, the correct answer is option 'B': All red fruit, tall 50%.
