| Video Discription | 🦊 In this GCSE Biology video, we explain how alleles, which can be dominant or recessive, determine an organism's phenotype, specifically using eye color as an example. It details that alleles written with uppercase letters, like 'B' for brown eyes, are dominant, and those with lowercase letters, like 'b' for blue eyes, are recessive. Dominant alleles express the trait even if only one copy is present, which is why brown eyes can appear in both homozygous (BB) and heterozygous (Bb) combinations. Conversely, blue eyes only appear in a homozygous recessive (bb) combination, where no dominant allele is present. For exams, it's crucial to understand and describe these differences between dominant and recessive alleles and between homozygous and heterozygous genotypes. 👋 Hi, we’re Launchpad Learning.
