5. Unicorn lily flowers have four different alleles for flower color: purple, magenta, orange, or silver. Based on the following crosses, explain the relationship between these three alleles in terms of which are dominant, recessive, or have another relationship. In the examples listed below, all parents are true-breeding. Purple x magenta → All F1 offspring are purple Silver x magenta → All F1 offspring are magenta Orange x silver →All F1 offspring are orange Purple x orange → All F1 offspring are purple Orange x magenta → All F1 offspring display flowers with orange & magenta petals

females. What chromosome likely carries the gene for this trait? Explain why this trait is
more common in males. Use a Punnett square to help demonstrate your explanation.
4. The hypothesis of blended inheritance (see slides from 8/24/22) states that an
offspring's traits are an intermediate form between the two parents' traits. The
incomplete dominance pattern of inheritance seems to support this idea at first glance.
However, when you investigate this further you can see that it actually does support the
discrete trait hypothesis. Explain why this is. Hint: set up several crosses of a trait
showing incomplete dominance, and look for examples where the phenotype of the
offspring is NOT a blend of the two parents.
