You have chosen to study the genetics of snapdragon flower color. True-breeding red-flowered plants crossed with true-breeding white-flowered plants generate all pink-flowered F1 offspring. When the F1 offspring are crossed, you get the following numbers of F2 offspring: 24 red, 54 pink, and 22 white. You interpret this inheritance pattern as

A. blending.

B. epistasis.

C. pleiotropy.

D. codominance.

E. incomplete dominance.

Angela House · Answer 1

Incomplete dominance.

Explanation:

Mendel is known as the father of genetics. He had explained the different inheritance pattern present in different organisms. The Mendel explained the law of segregation, law of independent assortment and concept of dominance.

The incomplete dominance may be defined as the inheritance pattern in which the dominant trait is unable to express it self completely in the heterozygous condition and blending traits are produced. Here, the red color is unable to express itself in the heterozygous condition and produce pink color.

Thus, the correct answer is option (E).
