Young scientists generally love to learn how certain traits can be explained by a direct combination of alleles from their parents. Here, they can examine how a phenotype is often expressed when one allele is recessive and the other is...

Each father and mother pass down traits to their children, who inherit combinations of their dominant or recessive alleles. But how do we know so much about genetics today? Hortensia Jimenez Diaz explains how studying pea plants revealed...

Overview of how chromosomes were first proposed as the carriers of Mendel's 'heritable factors' (what we now call 'genes'). [10:58]

This video explains how the double helix structure of DNA was discovered. [8:56]

Hank talks about population genetics, which helps to explain the evolution of populations over time by combing the principles of Mendel and Darwin, and by means of the Hardy-Weinberg equation. [11:03]

This lesson examines the following components of statistical analysis: mean, median, mode, inferential statistics, descriptive statistics, correlation, cause and effect, and spurious (false) correlation. It is 4 of 6 in the series titled...
