Among the products of a cross, those progeny that possess the phenotype of at least one of the individuals involved in the mating.
One sees invocation of the concept of parental type during test crosses in which genetic linkage is being assessed. With such crosses, the greater the frequency of parental types among progeny then the less genetic recombination that has occurred. By contrast, the greater the frequency of recombinant types, then, and perhaps not surprisingly, the more recombination that has occurred.
