WebApr 17, 2009 · The smaller the physical distance on the chromosome, the smaller the number of recombinants will be, and the larger the marker density we need to identify them. The relationship between recombination fraction and physical distance varies between species and across the genome within species. WebGenetic mutations are changes to your DNA sequence that happen during cell division when your cells make copies of themselves. Your DNA tells your body how to form and function. Genetic mutations could lead to genetic conditions like cancer, or they could help humans better adapt to their environment over time. Function Anatomy
