Andalusian chickens exhibit three colors; black, white, and blue. The gene controlling color has two alleles. When a true-breeding black Andalusion chicken is crossed with a true-breeding white Andalusion chicken, all offspring are blue.
What is the relationship between the two alleles controlling color? [ Select ] ["incomplete dominance", "codominance", "complete dominance"] What color(s) and in what ratios would you expect if you crossed 2 blues? [ Select ] ["1 black : 2 blue : 1 white", "1 black : 1 blue", "1 black : 1 blue : 1 white", "9 black : 3 blue : 4 white", "all blues", "all whites", "all blacks", "1 white : 1 blue"] What color(s) and in what ratios would you expect if you crossed a blue and a white?
