The Real Monkey's Uncle
Join commentators Dave Micklos and Jan Witkowski for a lively discussion of DNA in the news from world-renowned Cold Spring Harbor Laboratory! The Real Monkey's Uncle Marmosets are almost always born as fraternal twins; cells exchanged during development produce siblings that are a mixture of one another's cells. DNA testing showed that about half of male marmosets carry a mixture of sperm cells, and some marmoset babies inherit the DNA types of their uncles.
