Select the correct statement for the given figure.

Options

  1. Aa-yellow-bodied, white-eyed females
  2. BGenes were very loosely linked (showed very higher recombination).
  3. Ca-brown-bodied, red-eyed males
  4. Db-yellow-bodied, white-eyed females

Correct answer

A. a-yellow-bodied, white-eyed females

Step-by-step solution

For example Morgan hybridised yellow-bodied, white-eyed females to brown-bodied, red-eyed males and intercrossed their F 1 progeny. Morgan and his group also found that even when genes were grouped on the same chromosome, some genes were very tightly linked (showed very low recombination) (Figure 4.11, Cross A) while others were loosely linked (showed higher recombination) (Figure 4.11, Cross B).
