If you needed to order genes on a chromosome,you would perform
A)a test cross.
B)a two-point cross.
C)a three-point cross.
D)a SNP test.

Question

Quizplus · Accepted Answer

A three-point cross is the best choice for ordering genes on a chromosome because it allows for the determination of the order and relative distances between three genes on a chromosome by observing the recombination frequencies between them. Test crosses are used to determine the genotype of an individual, two-point crosses determine the relative positions of two genes, and SNP tests are used to detect variations in a single nucleotide.
