Question

. Corn kernels have an outer endosperm and an inner endosperm. A purple outer endosperm is dominant to a colorless (clear) outer endosperm. A yellow inner endosperm is dominant to a white inner endosperm. The inner endosperm color is not seen if the outer endosperm color is the dominant form. If the outer color is recessive or suppressed, the inner color is visible. (3 Points)
The genetic codes are as follows:
R = purple outer endosperm
r = colorless outer endosperm
Y = yellow inner endosperm
y = white inner endosperm
C = outer endosperm dominant color suppressor
c = no outer endosperm dominant color suppressor
a. What is the pattern of inheritance for corn kernel color?
1. Mendelian
2. Codominance
3. Incomplete Dominance
4. Polygenic
5. Epistasis
b. Write only the color you see when you look at the following corn kernels? One word answers only (ex: yellow)! Answers using more than one color are incorrect.
1. CcRrYY =
2. ccrrYy =
3. ccRrYy=

Answer 1

The pattern of inheritance is Epistasis 

1. CcRrYY= yellow 
2. ccrrYy= yellow 
3. ccRrYy= purple
