Ageneticist studying fruit flies hypothesizes that short wings are a recessive trait coded for by a single gene. which observation is most likely to have led her to form this hypothesis? flies with long wings are less likely to survive. flies with short wings prefer to mate with flies with long wings. flies have wing lengths ranging from very long to very short. flies with long wings can produce offspring with short wings.

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
