THE ESTIMATION OF RECOMBINATION VALUES IN BACKCROSS DATA WHEN PENETRANCE IS INCOMPLETE, WITH A SPECIAL REFERENCE TO ITS APPLICATION TO GENETIC ANALYSIS OF INSECTICIDE-RESISTANCE

Abstract

From the practical viewpoint attempts were made to establish methods for estimating the recombination values in three-point backcross data when the penetrance of a character was incomplete, and the viability of each gene employed or analyzed was not equal to that of the wild allele. Specifically, application of such methods was made to determine the locus for an insecticide-resistance gene on a given chromosome. The formulae proposed were practically independent of influences due to differential viability of genes and incomplete penetrance of the character to be analyzed.
