Over the course of seven years, Gregor Mendel grew more than 28,000 pea plants. The large amount of data he collected led him to postulate the rules of genetics as we understand them today. Scholars learn about Mendel, genetics, and...

Two individuals share 99.9 percent of their genetic codes, yet diversity is observed everywhere. Young scientists learn about diversity through hands-on activities and an experiment. They apply the concepts of independent assortment and...

Gregor Mendel was a monk who failed his teaching certification exam. He then dedicated his life to science and ended up creating the field of genetics. This presentation introduces the concepts of genetics and Punnett squares.

Dominate a lesson on genetic traits. Young scholars learn about the difference between dominant and recessive traits with an interactive lesson. An animation demonstrates Mendel's work on the inheritance of traits, and interactive...

Proving microscopic structures exist is a difficult task. Learn how scientists did just that in the mid-1800s as they set out to identify the cellular structures related to genetics. The online lesson explains the collection of work that...

Some traits only exist in males and some only in females. Pupils learn how the location of genes on sex chromosomes determines them using an interactive lesson. An animation illustrates how scientists know this to be true and shows how...

What's the difference between body cells and sex cells? Learners explore the question and the process of meiosis using an interactive lesson. An animation describes the discovery of meiosis and describes its phases for a detailed and...
