Monohybrid vs Dihybrid Crosses

Monohybrid Cross -- Punnett square contains four boxes -- a cross between two heterozygous individuals would reveal      -- a 1:2:1 genotype ratio      -- a 3:1 phenotype ratio -- probability an offspring will show a dominant phenotype is 75%

Dihybrid Cross -- Punnett square has sixteen boxes -- reveals two traits for both parents -- a cross between two heterozygous individuals would show a 9:3:3:1 phenotype ratio in the offspring
