Given this information for monsters of Mike’s species:
• Green body color [G] is dominant over yellow body color [g].
• Two eyes [E] are dominant over one eye [e].
• Long claws on toes [CC] are incompletely dominant over no claws
[Ć́Ć́] and [CĆ́] results in short claws
• Four fingers [F] are dominant over five fingers [f].
4. Color the monsters with the following genotypes:
GG

5. Draw and color the monsters with the following genotypes:
Gg/EE/CC/ff
gg/ee/CĆ/FF
Given this information for monsters of Sulley’s species:
• Purple body color [P] is co-dominant with blue body color [B] and
can result in a multi-color monster [PB].
• Horned ears [H] are dominant over no horns [h].
• Red eyes [R] are dominant over blue eyes [r].
• Long fur [L] is incompletely dominant over short fur [Ĺ]. [LĹ] Results
in average length hair.
