Codominance
Incomplete dominance [both traits blend - at molecular level]
i. Eye colour (mixed not spotted)
Incomplete dominance [both traits blend - at molecular level]
ii. Snap dragon (pink - not red/white)
Incomplete dominance [both traits blend - at molecular level]
iii. Wavy hair (not curly, not straight)
HSHS + HCHC = HSHC
straight + curly = wavy
