Having Six Fingers Is a Dominant Trait

The video explores the genetic condition polydactyly, often seen in Hemingway cats, and its relation to dominant alleles. It delves into cellular differentiation, the discovery of the hedgehog gene in fruit flies, and the role of the Sonic Hedgehog protein in development. The video explains how genetic mutations can lead to conditions like polydactyly and syndactyly, highlighting the complexity of gene expression and development.
