What is the difference b/t a co-dominance, simple dominance, incomplete dominance?

Question

Can you plz explain me and give examples cuz im confused about them. thnx!

Answer 1

1. Simple dominance is the way that Mendel described it. One form of the gene is dominant over the other form which is called recessive. Using T for tall and t for short:
TT and Tt are both tall. tt is short.
2. Codominant alleles are BOTH dominant. They both show up when they are both present. Using R for red hairs on horses and W for white hairs on horses:
RR is a red horse. WW is a white horse. RW is a roan horse that has both red hairs and white hairs on the same animal.
3. Incomplete dominance gives an intermediate (or in between) form of the trait when both alleles are present. Using R for red flowers and W for white flowers:
RR is red-flowered; WW is white-flowered; and RW is pink-flowered. This also works for crossing black and white to make gray, crossing long and short to make medium, crossing curly hair and straight hair to make wavy hair, etc.

Answer 2

imagine a difficulty,in this difficulty 2 frogs mate one is pink and the different is blue and there newborn will be a blend of white and blue IF it were co-dominance. IF their newborn is eco-friendly which will be incomplete dominance
