Phenotypic plasticity & recessive alleles (2025)
This activity provides a great opportunity for students to learn about some interesting exmples of genetics. The first section covers phenotypic plasticity, this is followed by a recessive allele causing a human disease. The final activity explores the 135 different polymorphisms of the human phenylalanine hydroxylase gene. This is a protein coding gene who's recessive alleles cause the human disease PKU. Genetic...
