Consider the following genotype frequencies:

ABC = 3
A++ = 54
+B+ = 215
A+C = 235
++C = 29
+++ = 5
+BC= 52
AB+= 92

How would you determine which phenotype undergoes double crossovers?

• A. The phenotypes with the highest frequencies
• B. The phenotypes with frequencies near the mean
• C. The phenotypes with the lowest frequencies
• D. The phenotypes that have a higher number of mutant alleles

Answer: (C)
