Question
A geneticist is using a three-point testcross to map three linked Drosophila recessive mutations called a, b, and c, where a is
associated with anomalous gait, b is associated with buckled wings, and c is associated with curved bristles. She first crosses
homozygous anomalous, buckled flies to homozygous curved flies. Next, she testcrosses the F1 progeny to anomalous, buckled,
curved flies. She obtains 1000 progeny distributed as shown. From this data, calculate the map distance between b and c.
