Incomplete Dominance

Incomplete Dominance

• Incomplete dominance is when both traits are expressed. The dominant gene does not fully cover the recessive. For instance, a white flower is crossed with a red flower resulting in a pink flower. The white and the red mix resulting in a mixture of the two. One phenotype is not dominant to the other.

Genotype

• When crossing two organisms you always use different letters and both of these letters are capital due to the fact they are both purebred. For example, you cross WW with  RR. Since this is an instant of incomplete dominance you will put BOTH letters for the offspring, RW. 

Phenotype

• As said previously, when crossing two different organisms in an instance of incomplete dominance both traits will mix creating a phenotype where the two original phenotypes are mixed. You will tend to see this happen in F1 generations but you can also cross heterozygous organisms and see incomplete dominance take place. 

• If you have a red and blue flower (RB) crossed with another red and blue flower in a punnett square 50% of that square will be purple. 

Reflection

I did not know of this till we covered it in class and i've always loved to learn about genetics. I found this topic VERY interesting because I was always curious before when learning about cross pollination. I feel as if there is more to add so if you know something else please leave it in the comments! I covered what we had learned about topic but if you feel as if it can be further explained I would love to read what you know! This is something you see everyday around you that not many people pay attention to.
