Text Solution

Verified by Experts

A more efficient mapping tochniquo is to construct based on the results of these-point test cross. If refers to analyzing the inheritance patterns of three alleles by test crossing a triple recessive heterozygote with a triple recessive homozygote. It enables to determine the distance between the three alleles and the order in which they are located on the chromosome. Double cross overs can be detected which will provide more accurate map distance.
