Usage: genetics; scientific

Examples

• The two genes are separated by approximately 50 morgans on the chromosome.
• Geneticists use morgans to map the relative positions of genes.
• The distance between these markers is measured in centimorgans, which are hundredths of morgans.
• Chromosome mapping requires precise measurements in morgans.
• The genetic map showed a distance of 20 morgans between the two loci.
