Question

The kernals on ears of corn come in a variety of colors and textures. The P gene controls color. The dominant P allele produces purple kernals. The recessive p allele produces yellow kernals. The S gene controls texture. The dominant S allele produces smooth kernals. The recessive s allele produces wrinkled kernals. If you perform a testcross with an individual that is PpSs, the expected phenotypic ratio for corn kernals in the next generation is

Select one:

a. 50% purple, smooth; 25% purple wrinkled; 25% yellow, wrinkled

b. 25% purple, smooth : 50% yellow, smooth : 25% purple, wrinkled

c. 25% purple, smooth : 25% purple, wrinkled : 25% yellow, smooth : 25% yellow, wrinkled

d. 25% yellow, smooth : 50% purple, wrinkled : 25% yellow, wrinkled

e. 9 purple, smooth : 3 purple wrinkled : 3 yellow, smooth : 1 yellow, wrinkled
