Essential vocabulary to describe genetic inheritance and gene expression.
Stated clearly - What is a gene?
Amoeba sisters - Alleles and Genes
Video by Genome British Columbia showing gene expression
Predicting Inheritance
Presentation describes Mendelian genetics - inheritance of mono-genic traits (determined by one gene)
Video describes how to complete a Punnett square to predict inheritance of one trait.
Describes the difference in the inheritance between independent and linked genes.
Video describes how to set up and solve a Punnett square for a dihybrid cross (two indepedent genes).
Pedigrees
Describes patterns of inheritance show in pedigrees charts that track traits across multiple generations.
Explore autosomal recessive trait and X-linked recessive trait tracking in pedigrees with the Amoeba Sisters!
The inheritance of traits is usually depicted using a pedigree chart. This video explains how to analyse pedigree charts to determine the pattern of inheritance.
This video explains how a single genetic mutation alters the structure of hemoglobin and leads to sickle-cell disease.
Short film that explore the evolutionary connection between an infectious disease, malaria, and a genetic condition, sickle cell disease.
