Genetic inheritance - AQA Our genes are inherited from our parents, and the different combinations of these genes make us unique. Mendel was curious about how traits were transferred from one generation to the next, so he set out to understand the principles of heredity in the mid-1860s. In females, 1 egg cell and 3 polar bodies are produced. In this tutorial, you will explore the genetic context of meiosis.
