Finding the Probabilities (Algebraically)
To start, take a mother with the genotype Tt and a father with the genotype tt. (T=dominant, tall, t= recessive, short)

For the mother, because there is one T out of the two traits, there is a 1/2 chance that she will pass on her dominant allele, and correspondingly, there is a 1/2 chance she will pass on the recessive one.

The father, no matter what, will pass on a t, so he has a 1/1 chance.

If we wanted to find the probability of getting an offspring with the genotype Tt, we would consider the multiple ways to get that. First off, we need the T from the mother, and theres a 1/2 chance of getting that. From the father, we need a t to complete the Tt...and theres a 1/1 chance of getting a t from the father. To combine these two probabilities, you must multiply them...so 1/2 x 1/1 = 1/2 There is a 50% chance of getting offspring with the genotype Tt.

Blood Type__
I read this article about how ZymeQuest is working on a technology that could convert all types of blood to O, by removing the sugar molecules that dictate blood type. 1211285414
