Biology 12412 Bell Ringers Copy the example EOC

Biology 12/4/12 Bell Ringers: Copy the example EOC question and the correct answer. 1. Which is responsible for most genotypic and phenotypic variation among humans? A meiosis C mitosis B budding D regeneration 2. Some flowers show incomplete dominance. If RR = white and R′R′ = red, which phenotypic ratio would be expected in the offspring of two pink flowers? A 4 RR : 0 RR′ : 0 R′R′ C 3 red : 0 pink : 1 white B 1 RR : 2 RR′ : 1 R′R′ D 1 red : 2 pink : 1 white 1 st period finish Bikini Bottom Genetics: Incomplete dominance and co- dominance side of ws.
