Inheritance: Part 2
If you inherit two copies of every gene, one from each parent, how do your cells know which version to use? Biology - Cells And DNA - Learning Points. Alleles, alternative forms of genes, can be dominant or recessive. Dominant alleles...

Introduction to Genetics: Mono Hybrid Cross and Inheritance Patterns
The video explains how different types of diagrams can be used to represent the possible outcomes of a mono hybrid cross, which refers to the inheritance of a characteristic controlled by one gene only. The video includes three examples...

Inherited Disorders and Embryo Screening: Understanding Cystic Fibrosis and Polydactyly
In this video, the speaker discusses two inherited disorders: cystic fibrosis and polydactyly. They explain how each disorder is inherited and the possible outcomes when couples who are carriers have children. The speaker also introduces...

Understanding Genetic Inheritance: How Genes Control Physical Characteristics
This video explains how physical characteristics in offspring are controlled by the interaction of genes inherited from each parent. It discusses the role of alleles, which are different forms of the same gene, and how multiple genes can...

Understanding Sex-Linked Genetic Disorders
This is a video that explains the concept of sex linked genetic disorders. The video begins by discussing chromosomes and how 22 pairs of chromosomes control characteristics, while one pair carries genes that determine sex (X&Y). The...

Albinism | Genetics, Different Types, and What You Need to Know
Lesson on Albinism. The genetic condition known as albinism is more aptly known as oculocutaneous albinism due to its ocular and cutaneous manifestations. An individual with albinism is colloquially known as an “albino”. Oculocutaneous...

The Evolution of Populations: Natural Selection, Genetic Drift, and Gene Flow
After going through Darwin's work, it's time to get up to speed on our current models of evolution. Much of what Darwin didn't know is now known and understood very well, so we can meticulously go through much of the evidence we see for...

Inheritance of X-Linked Genes
We all know that DNA is the molecule of heredity, but we didn't always know that. It had to be demonstrated empirically. As it happens, some of the first evidence put forth had to do with genes found on the X-chromosome of fruit flies,...
