Genetic Maps Are Based on Recombination Frequencies

question 24

Multiple Choice

Genetic maps are based on recombination frequencies.Because both odd and even numbers of crossovers can occur between any two gene loci,as the physical distance between two loci increases,the maximum recombination frequency levels off at 50%.However,suppose you discovered a species where only an even number of crossovers can occur between any two gene loci.In this case,as the physical distance between two loci increases,you would expect the maximum recombination frequency to

• A)remain at zero.
• B)increase with no limit.
• C)level off at 25%.
• D)level off at 75%.
• E)level off at 100%.
