The expected progeny plants of the F2 generation (pink flower x<span> pink flower) will be:
</span>1/4 = 25% RR (homozygous dominant)- phenotype: red
2/4 = 50% Rr (heterozygous) phenotype: pink
1/4 = 25% rr (homozygous recessive)phenotype: white
R- red
r- white
The genotypic ratio of the above cross will be 1:2:1, that is 1 homologous plant with axial flowers (AA), 2 heterozygous plants with axial flowers (Aa) and 1 homologous plant with terminal flower (aa).
