Essay
X, Y, and Z are linked genes. Based on testcross data, the frequency of recombination between genes X and Y was determined to be 33.1 map units. Between genes X and Z, the distance was 11.8 mu; between genes Y and Z, the distance was 21.3 mu.
-Is it possible for crossing-over to occur between two linked genes,yet for all of the resulting offspring to have parental genotypes?
