Genes Count

Simplify the teaching of basic genetics with this engaging cross-curricular science experiment. Using different kinds candy to represent the genes for determining eye shape in humans, young geneticists test the accuracy of Punnett...

In this gene cloning worksheet, students are given a gene sequence of DNA, plasmid DNA, 3 restriction enzymes, their cut patterns and a DNA ligase. They answer 6 questions about the results of using different restriction enzymes to cut...

An engaging video explains the mechanisms that cause changes to occur in genetic code. The narrator explains how duplication lengthens the genetic code and then highlights three examples of gene duplications and their resulting new traits.

Doctors sometimes order a karyotype, a picture of the chromosomes present in a single cell, in order to check for chromosomal abnormalities or rare diseases. The video explains the relationship among genes, chromosomes, and karyotypes....

How do organisms end up with such a wide variety of traits? It's in their genes! Kick off your inherited traits lesson using a brief video that covers alleles and genes. The narrator describes heterozygous and homozygous genotypes, how...

Chromosomes, genes, traits ... how are they all related? A short video introduces the many factors involved in heredity. Junior geneticists explore the transfer of chromosomes from parents to offspring, the proteins created by base pair...

Looks aren't everything. According to my biology teacher, it's what is inside you that really matters. The video explains gene expression and regulation in prokaryotes using the Order of the Operon. It includes a description of the...

Do you sneeze when you go from dark to light areas? Twenty-five percent of the population does! It turns out that the characteristic is due to genetic code. Explore why this happens with a video from the Veritasium playlist that breaks...

Could a population stay the exact same over time with no change in allele frequencies? The video explains the Hardy-Weinberg equilibrium theorem and the assumptions it requires. It discusses mutation, migration, gene flow, genetic drift,...

Do you know how many chromosomes humans have? Do you know how many of those chromosomes we share with the chimpanzee? A perfect introduction to DNA for your middle schoolers, this video uses a ton of visuals to clearly illustrate the...
