Mapping eakaryote chromosomes by recombination - Mapping by recombinant frequency - Three-point testcross

4 important questions on Mapping eakaryote chromosomes by recombination - Mapping by recombinant frequency - Three-point testcross

Are all the loci linked when the RF values are all considerably less than 50 percent? Because the v and cv loci have the largest RF value, they must be closest/farthest apart.

Yes, farthest apart

Could the drafted map equally well be drawn with the placement of the loci inverted?

Yes

Do linkage maps map the loci in relation to one another?

Merely, we do not know where the loci are on a chromosome—or even which specific chromosome they are on.

What could cause us to underestimate the distance between the v and the cv loci?

  • Did not account for the rarest classes
  • Did not count twice for double recombinants.
