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.

What is the scientific term for having too many fingers or toes?

What are some other species besides cats that can exhibit polydactyly?

How does the presence of Sonic Hedgehog protein influence the development of fingers and toes?

Explain how a mutation in the Sonic Hedgehog gene can lead to polydactyly.

What is syndactyly and how does it differ from polydactyly?
