Some flowers are controlled by codominance. Red flowers (F^RF^R), blue flowers (F^BF^B) and Speckled flowers (F^RF^B).

Cross a red flower with a speckled flower. What is the phenotypic ratio?

A red flowered plant (RR) is crossed with a white flowered plant (WW). The gene for petal color in these plants expresses incomplete dominance. What percentage of the offspring will have red (RR) flowers?

A long-haired female rabbit and a short-haired male rabbit produced this offspring with a medium-length coat:

What are the 4 possible phenotypes for human blood type?

Which of the follow blood types shows the inheritance pattern of codominance?

Blood type is controlled by the inheritance of any two of the following alleles: |^A, |^B, or i. |^A codes for type A blood. |^B Codes for Type B blood. Both |^A and |^B are codominant. The i allele is recessive and will cause Type O blood whenever two copies of the allele are present.

If a mother has Type AB blood (|^A|^B) and a father has Type O blood (ii), what percentage of their children are likely to have Type A blood?

Which allele combination represents a male who has an X-linked recessive disorder?

Who are sex linked disorders most often observed in?

True or False: Males always inherit their X chromosome from their mother

Red-green color blindness is a sex-linked trait. If a female carrier is crossed with a colorblind male, what would go in the missing places of the Punnett Square?
