How to solve problems with crossing over, map units and centiMorgans

The percent recombination between two markers indicates the map distance between them: 1% recombination = 1 map unit (m.u.). In genetic genealogy, a centiMorgan (cM) or map unit (m.u.) is a unit of recombinant frequency which is used to measure genetic distance. It is often used to imply distance along a chromosome, and takes into account how often recombination occurs in a region. #genetics #MapUnit #SentiMorgan #crossingover #crossingOver #synapsis #linkedGenes #geneticRecombination #crossingOverInMeiosisI #crossingOverOfChromosomes #homologousChromosomes #nonsisterChromatids #sisterChromatids #mendelianGenetics #chromosomalCrossover #genes #fruitFlyGenetics #vestigialWings #normalWings #geneticsInFruitFlies #NikolaysGeneticsLessons #ThomasHuntMorgan #fruitFlies #meiosis #recombinantChromosomes #alfredSturtevant
