Caption: The researchers placed the more than 1,000 single-cell yeast offspring in a grid pattern on plates such as this one, and subjected each plate to a different condition, including different temperatures, food sources and presence of various drugs. Offspring thrived (large dots) or did not thrive (small dots) depending on their genetic make-up. Researchers examined the yeast to find out how much of their ability to survive was inherited from their parents.
