Mendel: Extra Biology Credit

are in the F1 generation. When I breed the F1 generation I ended up with the F2 generation.  For the F1 generation I selected a six foot pea plant and a short pea plant and crossed them. In the F1 generation I noticed that all the offspring were tall and didin’t even show short. In the F2 generation I  crossed 2 tall pea plants and noticed that ¾ of the offsprings were as tall as the tall plants in the P generation. I also noticed that ¼ of the offspring were as short as the short plants in the P generation. I noticed that one trait kept disappearing in the F1 generation. I gave a capital letter to the trait which showed up in the first generation and the small letter to the trait which was hidden in the F1 generation. The trait that appeared in the F1 generation I called dominant and the traits that were hidden I called recessive. I observed that some tall plants crossed with each other showed both and tall and short offspring. I came to the conclusion that an organism may look alike but have different gene combinations. The way an organism looks like is it’s phenotype.  Organisms which have two different genes are termed heterozygous. A listing of the letters which stand for the genetic makeup of an organism is termed its genotype.  I recorded that the genotype of  a tall plant is TT and the genotype of one tall allele and one small allele is Tt. An organism is homozygous for a trait if its two alleles for a trait are the same (TT). An organism is hetozygous for a trait it its two alleles for the trait are different (Tt). Dad are you with me? I think I broke the code of Genetics which is the study of heredity. Aren’t you very proud of my accomplishment, I think that my discovery will make a big impact in the years to come. Well got to go ,just wanted to let you know what I have been up to and let you know about my research. Well take care Lots of love                                                             Gregory Mendel
