A ____ is best used to demonstrate the linkage of two genes.
A) monohybrid cross
B) dihybrid cross
C) monohybrid test cross
D) two-allele test cross
E) two-point test cross
Two-Point Test Cross
A genetic cross used to test for linkage; individuals heterozygous at two loci are crossed with individuals who are homozygous recessive at those loci.
Linkage
The tendency for a group of genes locatedon the same chromosome to be inherited togetherin successive generations
Genes
Segments of DNA located on chromosomes that carry the instructions for the development, functioning, growth, and reproduction of organisms.

Final Answer :
E
Explanation :
A two-point test cross is specifically designed to analyze the linkage between two genes by crossing an individual heterozygous for both genes with an individual homozygous recessive for both genes, allowing for the observation of recombinant and parental genotypes.
