Question

In a dihybrid test cross in Drosophila between purple eye, vestigial wings with normal red eye, long wings are as follows. Calculate RF.

• A. 10.7%
• B. 25.6%
• C. 5.3%
• D. 40.8%

Answer 1

Answer:

A. 10.7%

RF = (Recombinants / total number of organisms) x 100 = [(151 + 154) / (1339 + 151 + 154 + 1195)] × 100 = 10.7%
