Tail length in dogs is often determined by incomplete dominance. Pups of long-tailed (TT) and short-tailed (SS) parents often split the difference and have medium-length tails (TS). If we crossed two heterozygous dogs what is the probability that the offspring would have long-length tails?

This picture shows what the red blood cell of someone with sickle cell anemia. This disorder is carried on the X chromosome and is most common in sub-saharan populations. What type of inheritance pattern must it follow?
codominance

incomplete dominance
Rhododendrons exhibit codominance. In the case of rhododendrons, the crossing of a red and white flower may yield a flower that has both red and white patches (heterozygous). If a red flower were to cross with a heterozygous flower, what would the probability of producing a red flower be?

Hemophilia is a sex-linked recessive trait. The allele for normal blood clotting is (XH) and inability to blood clot is (Xn).
