How many people are you made up of? Mosaicism in genetics.


Reading a NY Times Science article on the prevalence of genetic mosaicism is as awe-inspiring as hearing that Voyager 1 is in interstellar space! One woman had eggs that represented two different “people” within her, and mothers of sons show Y chromosome integration. Anyway, this article is well worth a read if you have a few moments and want to be excited by science all over again. ¬†Genetics is of particular interest to me, since those close to me are affected by its vagaries.
