Post-Lab Questions

1. Determine the percentage of crossovers. To do this, divide the number of crossovers by the total number, and multiply it by 100.

2. Determine the map distance. To do this, divide the percentage of crossover by two. Note that the number is divided by two because crossover occurs once between two chromosomes.
