What generalization did Mendel propose based on his observations on dihybrid crosses?

Options

  1. AMendel's Law of Segregation
  2. BMendel's Law of Dominance
  3. CMendel's Law of Independent Assortment
  4. DMendel's Law of Incomplete Dominance

Correct answer

C. Mendel's Law of Independent Assortment

Step-by-step solution

In the dihybrid cross (Figure 4.7), the phenotypes round, yellow; wrinkled, yellow; round, green and wrinkled, green appeared in the ratio 9:3:3:1. Such a ratio was observed for several pairs of characters that Mendel studied. The ratio of 9:3:3:1 can be derived as a combination series of 3 yellow: 1 green, with 3 round : 1 wrinkled. This derivation can be written as follows: (3 Round : 1 Wrinkled) (3 Yellow : 1 Green) = 9 Round, Yellow : 3 Wrinkled, Yellow: 3 Round, Green : 1 Wrinkled, Green Based upon such observ
