reciprocal cross

a pair of crosses in which the PHENOTYPES of the partners are reversed. Thus, in humans the following are reciprocal crosses:

Different results from the two crosses indicate SEX LINKAGE of the gene controlling the character.

In sperm concentration experiments, the sperm concentrations that yielded maximum fertilization rates with the least abnormality in subsequent development were 4.66 x [10.sup.7] sperm/mL for the DG cross and 2.6 x [10.sup.7] sperm/mL for the reciprocal cross GD.
Summed over all treatments, there were 120 crosses with two reciprocal crosses per cross plus replicate matings within each reciprocal cross.
The second objective of this study was to use computer simulation to investigate the probability that rare alleles will be retained and to determine the average number of alleles lost after several regeneration cycles because of different numbers of seeds being taken from each pollinated plant and the use of different pollination methods [e.g., random pollen, chain cross, paired cross (with or without reciprocal cross), and self-pollination].
