Dear student ....Reciprocal crosses are crosses between different genetic stocks, where the sexes of the parents are reversed. In the case of strains A and B, (A×B) and (B×A) are reciprocal crosses while back cross is the mating of a hybrid organism with one of its parents ....With Regards ....Mahima ....(askIITians Forum Expert )

Back cross is the cross that involves the mating of the F1 hybrid with one of its parent to achieve offspring with a genetic identity which is closer to that of the parent.

Reciprocal cross is a cross a pair of crosses to test the role of parental sex on inheritance pattern, it is done between a male of one strain and a female of another, and vice versa.
Example: genotype A(female) X genotype B(male) and genotype B(female) X genotype A(male).
