d. 75%





e. 100%

In snapdragons, heterozygotes have pink flowers, whereas homozygotes have red or white flowers. When plants w?
The answer should be e: 100%





Assume R codes for red colour and r codes for white colour.





To have red flowers, the genotype must be RR. To have white flowers, genotype must be rr. To have pink, genotype must be Rr.





Crossing red flowers (RR) with white flowers (rr) in the punnet square will result in all 4 results being (Rr), which means 100% pink flowers.
Reply:50%





The possibilities for offspring are:





Pp Pp pp and pp





I used the letter P for pink on the punnet square.
