If b represents the allele for black eyes (dominant) and b represents the allele for orange eyes (recessive), what would be the genotypic ratio of a cross between a heterozygous black-eyed mendalien and an orange-eyed mendalien? if b represents the allele for black eyes (dominant) and b represents the allele for orange eyes (recessive), what would be the genotypic ratio of a cross between a heterozygous black-eyed mendalien and an orange-eyed mendalien? 1 homozygous black (bb): 0 heterozygote (black) (bb): 1 homozygous orange (bb) 1 homozygous black (bb): 1 heterozygote (black) (bb): 1 homozygous orange (bb) 0 homozygous black (bb): 0 heterozygote (black) (bb): 1 homozygous orange (bb) 0 homozygous black (bb): 1 heterozygote (black) (bb): 1 homozygous orange (bb) 2 homozygous black (bb): 1 heterozygote (black) (bb): 1 homozygous orange (bb)
