During a mapping experiment the number of observed double crossover events will always equal the number of expected crossover events.

True or False

Solution

Answer:

False

Explanation:

A positive interference value results when the actual number of double crossovers observed is less than the number of double crossovers expected from the single crossover frequencies. Thus positive interference indicates that a crossover inhibits or interferes with the occurrence of a second crossover nearby.

Conversely, a negative interference value, where more double crossovers occur than expected, suggests that a crossover event can stimulate additional crossover events in the same region of the chromosome
