Non-mendelian inheritance

Throughout this course, you will learn about the genome and how alterations of the genetic code can lead to human disease. However, although we often talk about conditions that result …

X-linked recessive inheritance

In this video, we learnt about X-linked recessive inheritance. X-linked recessive conditions are caused by a gene alteration on the X chromosome. As males have only one X chromosome, if …

Autosomal recessive inheritance

In this video, we learnt about autosomal recessive inheritance, where an affected individual has a mutation in both genes of a pair. If an individual has a mutation in only …

Sharing stories: Heleni

In this video, we hear the story of Heleni, who has been diagnosed with two autosomal dominant conditions: multiple epiphyseal dysplasia (MED) inherited from her mother and a genetic condition …

Autosomal dominant inheritance

In this video, we learnt about autosomal dominant inheritance, where an affected individual has a mutation in one gene of a pair. The main features of autosomal dominant inheritance pattern …

Understanding a pedigree

Doctors can use a pedigree to show how genetic disorders are inherited in a family. They can use this to work out the probability that someone in a family will …

Errors in recombination

Structural abnormalities Prior to segregation in meiosis, homologous chromosomes pair and genetic material is swapped. This is known as recombination and is key to ensuring offspring have different genetic traits …

What causes cancer?

This picture shows the acquisition of mutations through the lifetime of a cell as it divides – from a single celled fertilized egg through to becoming a cancer cell. The …

Errors in replication

During this video, we will look at how copying errors are introduced and the types of replication errors that occur. Embedding your knowledge Now that you’ve watched the video, you …

Errors in segregation

During this video, we will learn about how errors in the segregation of chromosomes can lead to genetic disorders such as Down syndrome, Patau syndrome and Edwards syndrome. Talking point …
