Answer: 46%
Step-by-step explanation:
Recombination frequency =Number of recombinant offspring ÷ total number of offspring × 100%
Number of recombinant offspring= 46 ( number of offspring with the same genetic combination as the parent which in this case are the tall antennae TA)
Total number of offspring = 46+7+5+42= 100
Recombination frequency= 46/100 × 100%
=46%
