What is the genotypic ratio/frequency of the F1 generation from this cross? 5. In certain flowers, a cross between a homozygous red and a homozygous white will always produce offspring with pink flowers. Diagram and explain this phenomenon. 6. If the pink flowers (from #5) from the F1 generation were crossed, what would be the resulting phenotypic and genotypic ratios for the F2 generation?.
