4 steps. Step 1: 'LAW OF SEGREGATION: Each organism has TWO alleles for each gene. During gamete (sex cell) formation, these alleles SEPARATE so each gamete gets only ONE allele.' Show: parent Bb → gametes get either B or b, never both. Step 2: 'Why this matters: When two Bb parents reproduce, their
