In the given example, the color of the fruit flesh has two known phenotype colors: the red and the yellow. The second cross showed the a set of offspring having yellow fruits despite its parents having red fruits. Thus, the yellow fruit character is the recessive phenotype.
In tomatoes, the flesh can be either red or yellow. The following crosses involving plants of these two phenotypes are made.
a. What phenotype is dominant?
b. What are the genotypes of the parents and offspring in each case?
