DNA Research #DNA Explain a Centimorgan #dna

Barry Sieger


Can someone explain how Centimorgans predict close relationships between
individuals? I know a centiMorgan (cM) is a measurement of how likely a
segment of DNA is to recombine >from one generation to the next. It's also
a measure of distance. I read the the explanation on isogg.org but still
don't get why the more cM's your DNA has vs another individual, the more
you're related. They hadn't invented cM's when I studied genetics.

PS I'll be giving a talk on DNA to my local Jewish Genealogy Society
group & it would be nice to understand Centimorgans before attempting to
explain it.
