If a pure Black bird ($ ext{Bl}/ ext{Bl}$) is crossed with a pure Splash bird ($ ext{Bl}^+/ ext{Bl}^+$), what is the guaranteed outcome for the offspring?
Answer
Every single chick produced will be Blue ($ ext{Bl}/ ext{Bl}^+$)
Crossing a pure Black bird with a pure Splash bird results in every chick inheriting one copy of each allele, leading to the intermediate Blue phenotype ($ ext{Bl}/ ext{Bl}^+$).
