red flowers show incomplete dominance over yellow flowers. the intermediate color is orange. cross an orange flower with another orange flower. what is the genotype and phenotype?

Try using a punnet square. Remember RR x YY = RY (Orange)

RY x RY = 1RR / 2RY / 1RR

Explanation:

use a 4 square punnet

Monohybrid cross will always be

1 RR / 2Heterozygous / 1 YY Genotype

1 Red / 2 Orange / 1 Yellow Phenotype

(In other cases 1 Domiant / 2 Heterozygous / 1 Recessive)
