genotype

Why would genotype TT be larger thant Tt or tt? This was very hard for me to figure out when reading but after stairing at the picture for a little while longer I think I may have discovered why. A capitol T satand for the dominant and of course the lower case is the recessive. So when a plant is growing larger than the the rest of the plants in the area and of the same type that just mean that it received more dominant alleles during fertilization than the rest. The interesting part is when they are mixed. I can just think about how big the plants could be if they were able to get more dominant alleles more often instead of being mixed.The reason they do not is because it all depends on the ground a plant is planted in. I i take beans and plant them in Georgia red clay then the obvious result would be if they grew then they would be very weak and small plants. That results means that all the beans received from this soil was mostly just recessive alleles. Now we can plant them somewhere else, say an old corn field, all the corn died off about a year ago and it has been plowed. This is the place to go to plant these beans. Now on the outer edge may be the area where they will be mixed like Tt but as you move toward the heart of the field then there will be more nutrients there for genotype TT.
