Blood type doesn't fall into the category of dominant/recessive genes exactly; rather it combines this with the properties of incomplete dominance. Ignoring the Rh factor, there are 3 alleles for blood type, I^a,I^b, and i. You will be type A if you have I^a I^a or I^a i and type B if you have I^b I^b or I^b i. You can also get type AB by having the combination I^a I^b or be type O if you have i i. If you need to use dominant/recessive, you can say the A and B allele are dominant over the O allele and codominant with one another.

Answer: There will be a number of 25600 bacteria after 2 hours.
Explanation: This problem requires some simple math to solve.
We were told that E. coli doubles approximately every 15 minutes. Meaning that, after just 15 minutes, our colony of 100 bacteria is now a colony of 200 bacteria and so forth:
100 * 2^1 = 200
There are 4 15-minute periods in an hour, thus there are 8 15-minute periods in two hours. Therefore, the bacteria will have doubled their population size 8 times:
100 * 2^8 = 25,600
