Mendel discovered dominant/recessive traits by studying 28,000 pea plants

Brown eyes are dominant over blue - two blue-eyed parents always have blue-eyed children

Cat coat colors follow complex genetics - calico cats are almost always female

Incomplete dominance creates intermediate phenotypes like pink flowers from red x white

Blood type follows codominance - AB individuals express both A and B antigens

X-linked traits like color blindness affect males more than females (8% vs 0.5%)

CRISPR can edit genes with unprecedented precision - revolutionizing genetics

Modern corn looks nothing like its wild ancestor due to selective breeding
