______ used the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes.

Assertion: When two genes in a dihybrid cross were situated on the same chromosome, the proportion of parental gene combinations were much higher than the non-parental type. Reason: This is due to the physical association or linkage of the two genes.
