Show genotypes for paren e genetic explanation for these results? Show genotypes for parents, the Fi, and the generations. Make sure to identify the color of each pod present.

Explanation / Answer

The genetic explanation for the results would be Incomplete dominance.

The Orange flowers have complete dominance over Pink flowers. So all F1 progeny have orange flowers and some F2 progeny have White flowers because it shows a bit of incomplete dominance in this case

Parents - Rr ( Orange)     Pp (Pink)

F1 - RPrp (Orange)

F2 - rrpp ( Pink)
