From the Punnet square, the phenotype of the F2 generation will be 1 red radish (RR), 2 purple radishes (Rr), and 1 white radish (rr).
What is the phenotype ofthe F2 generation?
The phenotype of an organism is the physical expression of the genotype of the organism.
The dominant trait is always expressed while the recessive trait is expressed only in the absence of the dominant trait.
Assuming R allele be dominant allele over r allele.
The genotypes and phenotypes will be as follows:
RR - red radish
rr - white radish
Rr - purple radish
Parental generation: RR x rr
F1 generation: Rr Rr Rr Rr
The F1 generation are all purple radish.
The F1 generation then self-pollinates:
Using a Punnet square:
R | r
R | RR | Rr
r Rr | rr
The F2 generation is RR, Rr, Rr and rr
Therefore, the phenotype of the F2 generation will be 1 red radish (RR), 2 purple radishes (Rr), and 1 white radish (rr)
