Answer:
In order to produce pink carnation flowers, he will need one red (RR) and one white (WW) flower.
Step-by-step explanation:
To get a pink flower with the RW genotype, we need one red (RR) and one white (WW) flower.
This type of inheritance is called incomplete dominance, which means that the dominant allele does not completely prevent the effects of the recessive allele from being expressed. This results in the offspring's trait being equal to the mix of its parents' traits. When we mix the red and white color, we get pink.
In the given scenario, the Punnett sqaure will look like this:
W W
R RW RW
R RW RW
