I = Inflated, i = constricted. Given that the phenotype of F1 progeny is inflated pods and that the parents are true-breeding, which of the following is not a possible genotype of parents?
  • a)
    Parent 1: II; Parent 2: ii
  • b)
    Parent 1: II; Parent 2: II
  • c)
    Parent 1: ii; Parent 2: ii
  • d)
    Parent 1: ii; Parent 2: II
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
I = Inflated, i = constricted. Given that the phenotype of F1 progeny ...
Inflated is the dominant phenotype. So, it can be expressed in two genotypes: II and Ii. The F1 progeny can have it in all the mentioned cases except when both parents are recessive ii.

Understanding the Genetics of Pod Shape
When analyzing the inheritance of traits like pod shape in plants, it is crucial to understand the genotypes of the parents involved. Here, we have two phenotypes: inflated (I) and constricted (i).
Phenotype of F1 Progeny
- The F1 progeny shows an inflated phenotype (I) indicating that the inflated trait is dominant over the constricted trait.
True-Breeding Parents
- True-breeding means that the parents have homozygous genotypes, ensuring that they will consistently pass on the same allele to their offspring.
Analyzing Possible Genotypes
1. Parent 1: II; Parent 2: ii
- Possible. The offspring (F1) will all be Ii (inflated).
2. Parent 1: II; Parent 2: II
- Possible. All offspring will be II (inflated).
3. Parent 1: ii; Parent 2: ii
- Not possible. Both parents are homozygous recessive, leading to offspring that are also ii (constricted).
4. Parent 1: ii; Parent 2: II
- Possible. All offspring will be Ii (inflated).
Correct Answer: Option C
- The genotype combination of Parent 1: ii and Parent 2: ii cannot produce any inflated pod offspring, as they would all be constricted. Therefore, this pairing cannot produce the observed F1 phenotype of inflated pods, making option C the correct answer.
