By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome.
It is possible to determine the approximate distance between genetic markers using cytogenetic mapping, but not the exact distance (number of base pairs). Radiation hybrid mapping uses radiation, such as x-rays, to break the DNA into fragments.
Instructional Activity II: Hershey–Chase Experiments. This second activity asks students to examine the work of Hershey and Chase in an efort to identify the source of genetic information and draw conclusions to support the hypothesis that DNA, not protein, is the genetic material.
Genetic maps provide an outline for the location of genes within a genome, and they estimate the distance between genes and genetic markers on the basis of the recombination frequency during meiosis. Physical maps provide detailed information about the physical distance between the genes.
Discover the fascinating world of genetic recombination and gene mapping. Learn how the distance between genes on a chromosome influences their likelihood to recombine. Dive into the concept of centimorgans, the unit of measurement for gene distance, and how it relates to the frequency of recombination. Created by Efrat Bruck.

Start Unit test. DNA helps make us who we are, but how exactly does it work? In this unit, we'll examine the nitty gritty of replication, transcription, and translation, and learn how seemingly small mutations can have a big impact on our lives.
