How to find if two genes are linked or not

We can see if two genes are linked, and how tightly, by using data from genetic crosses to calculate the recombination frequency. 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. #Gene #geneLinkage #chromosomeCrossingOver #DNA #mRNA #geneticMap #ThomasHuntMorgan #fruitFlies #CrossingOver #meiosis #recombinantChromosomes #homologousChromosomes #genetics #alfredSturtevant #educationalVideos #scienceVideos #highSchoolScience #GeneticRecombinationAwardWinningWork #GeneMappingLiteratureSubject #EducationWord #chromosomalInheritance #genes #alleles #biology #apBiology #NikolaysGeneticsLessons
