GCSE Biology - Why We Inherit Diseases From Our Family - Polydactyly & Cystic Fibrosis #75

The video tutorial discusses inherited disorders, focusing on polydactyly and cystic fibrosis. Polydactyly is caused by a dominant allele, while cystic fibrosis is due to a recessive allele. Genetic diagrams illustrate how these conditions are inherited. The video also covers embryo screening, a process to detect genetic disorders in embryos, and discusses its ethical implications, including potential benefits and concerns.

What are inherited disorders and how can they be passed on?

Explain the condition of polydactyly and its genetic basis.

What is the probability of having an offspring with polydactyly when crossing a heterozygous individual with a homozygous normal individual?

Describe cystic fibrosis and how it is inherited.

What is the significance of being a carrier for cystic fibrosis?

What is embryo screening and what are its potential implications?

Discuss the advantages and concerns associated with embryonic screening.
