7.L.4A.3 Develop and use models (Punnett squares) to describe and predict patterns of the inheritance of single genetic traits from parent to offspring (including dominant and recessive traits, incomplete dominance, and codominance).
How are traits passed from parents to offspring? A trait is a characteristic such as color or size that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. In this Virtual Lab you will use a Punnett square to find possible gene combinations and to create a fictitious animal.

There has been an earthquake at a local bay area hospital. Nurse Ratchet, only on her second day on the job, was assigned to care for the babies in the nursery. In her haste to evacuate the hospital, Nurse Ratchet neglected to put identification bracelets on the newborn babies.
Your job is to utilize your knowledge of genetics and heredity in order to the deliver the babies to their correct parents. To solve the mystery, you must analyze various genetic traits in order to match babies to their parents. You will need a solid understanding of Punnett squares, blood types, dominant, recessive, and co-dominant genes in order to solve the case. If you get stuck, go back to the tutorials.There are three different scenarios and levels of difficulty. If you solve the first level, challenge yourself to solve a more difficult case. Good Luck!
