Answer :
Certainly! To analyze this problem, let's break it down step by step considering the principles of Mendelian genetics and the resulting phenotype ratios.
1. Parental Generation: Your original parental generation consists of:
- Two types: R (smooth seeds) and r (wrinkled seeds).
2. Creating F1 Generation:
- When you cross homozygous dominant (RR) with homozygous recessive (rr), all the offspring in the F1 generation will be heterozygous (Rr).
- Thus, the genetic makeup of the F1 generation is:
- 100% heterozygous Rr.
3. Phenotypic Expression in F1 Generation:
- Since R (smooth seeds) is dominant over r (wrinkled seeds), all heterozygous Rr individuals will express the dominant phenotype.
- Therefore, the entire F1 generation will have smooth seeds.
Summarizing the results:
- The entire F1 generation will be heterozygous (Rr).
- The entire F1 generation will have the smooth seeds phenotype.
Therefore, the correct statements among those given are:
- The entire F1 generation will be hybrid (heterozygous).
- The entire generation will have smooth seeds.
