Genetics - Lost and Found: Crash Course History of Science
Sometimes trail blazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again.

Great Minds: Gregor Mendel
How would you feel if you made a huge scientific discovery, published it everywhere, and shared it with every scientist, only to have it ignored for 35 years because no one understood your genius? Unfortunately, Gregor Mendel died before...

Introduction to Heredity
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...

What Are Mendel and Genetic Crosses?
Darwin and others hypothesized evolution, but they never explained how it worked genetically. The video introduces Mendel and his hypothesis, which scientists have now proved. It explains how he created the hypothesis and what...

Non-Mendelian Genetics
Any pattern of inheritance that does not follow Mendel's laws uses non-Mendelian inheritance. The video explains this type of genetics with many guided practice problems. It covers incomplete dominance, codominance, and sex-linked traits.

Heredity
Ear wax, either wet or dry, is inherited on chromosome 16. The narrator of a video about heredity uses ear wax to introduce the concepts of alleles, dominant and recessive traits, and heterozygous and homozygous genotypes.

Punnett Squares and Sex-Linked Traits
Until the 1960s, the life expectancy of a hemophiliac was only 11 years. An informative video explains how to solve a Punnett square when there is a sex-linked trait — in this case hemophilia. It includes a discussion of the xy...
