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...

After learning to calculate probabilities for single examples of genetic crosses in a previous lecture, students are exposed to the concept that allele and genotype frequencies in a population remain in constant equilibrium. A reasonable...

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...

Pupils puzzled by pedigree charts? Not anymore! Show them proper pedigree protocol using a short video from an excellent biology playlist. Content includes pedigree symbols and terminology, interpreting pedigrees of various lengths, and...

Scholars often find new vocabulary overwhelming—help break it down for them. A helpful video addresses the vocabulary associated with genetics and cell division. It offers the definition of each and a short explanation. Cartoon graphics...

Introduce young biologists to monohybrid crosses and simple Punnett Squares. It includes explanations of dominant versus recessive and genotype versus phenotype by exploring different genetic combinations of guinea pigs.
