Question

When more than two loci are investigated together (e.g., three-point testcross), a researcher can determine whether the genes being studied are linked, how far apart these genes are from one another, and: the specific nucleotide sequences of these genes. the gene order. how the genes acquire mutations. all of the possible alleles for these genes. None of the answers is correct. When more than two loci are investigated together (e.g., three-point testcross), a researcher can determine whether the genes being studied are linked, how far apart these genes are from one another, and:

Explanation / Answer

The correct answer is gene order. We can do it by simply checking the double cross over progenies and parental progenies. From the sequence of the double cross over, which ever allele is changing in DCO progenies, we can it is in the middle and from the distance data we can determine the order of the gene on map.
