Codominance
In this video we are now going to look at codominance. You need to understand the difference between genotype and phenotype. The genotype is the set of genes. The phenotype are the physical characteristics that are coded for by the...

Mendelian Genetics and Punnett Squares
For all of human history, we've been aware of heredity. Children look like their parents. But why? When Gregor Mendel pioneered the field of genetics, he began to try to answer that question, and now that we know about chromosomes, all...

Fundamentals of Genetics: Genotype and Phenotype
In this program Mendel's work is explored in greater detail by using probability to make predictions of the inheritance of specific traits. The use of the Punnett Square is illustrated through easy-to-understand animations. Other...

How Mendel's Pea Plants Helped Us Understand Genetics
A brief animation introduces heredity to your beginning biologists. They will meet Gregor Mendel's green and yellow peas, dominant and recessive traits, homozygous and heterozygous alleles, and Punnett squares. In this cartoon animation,...

Mendelian Genetics and Inheritance
Introduce your biologists to Gregor Mendel, the man responsible for Mendelian genetics. The resource explains the experiment that made him famous and sparked interest in genetics everywhere. Also take a closer look at Huntington's...

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...

Hardy-Weinberg Principle
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...

Variation in a Species
If there are no extenuating environmental factors to ensure competition in a species, then variation is achieved by random mutation. This resource may be more useful after viewers are introduced to the concepts of alleles and the...
