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
