In the plants that they studied, the genes for pollen shape and flower color are located on the same chromosome (pair) as each other, ... T. H. Morgan and his grad students, who studied fruitflies, found that the farther apart two genes are on a chromosome, the more likely there is to be crossing over between those two genes.

Chromosomal crossover (or crossing over ) is the exchange of genetic material between homologous chromosomes. This often occurs during prophase 1 of meiosis in a process called synapsis. Synapsis b...

Genetic linkage - Wikipedia, the free encyclopedia
Genetic linkage occurs when particular genetic loci or alleles for genes are inherited jointly. Genetic loci on the same chromosome are physically close to one another and tend to stay together durin...

Here, we report the isolation and analysis of point mutations in two previously uncharacterized D. melanogaster RP genes located in the centric heterochromatin of the second chromosome, namely RpL38 and RpL5. We find that these mutants display the classic Minute phenotypes of small adult bristles and delayed development.

Biology, Chapter Twelve, Notes. Science-Biology ... They occur close to each other on the same chromosome. The farther apart two genes are located on a chromosome, the more likely a cross-over will occur. Researchers use recombinant percentages to construct chromosome maps showing relative gene positions.

However, genes located on the same chromosome tend to occur together fre-quently, especially if they are located close together, because the chance of a break occurring between them is small. The farther apart two genes are on a chromosome the greater is the chance for a break to occur between them.
