The genetics problem of the Punnet square (P-square for short) A homozygous (pure) dominant that means two alleles that are the same that are capital letters and refers having two identical alleles for a single trait. (TT) A heterozygous (hybrid) recessive that means Genotypes made of two different alleles (rr)

__Step 1:__ If the questions says that cross two organisms with the following genotypes are Tt & tt. To cross short pea plant with one that is heterozygous for tall. The vocab was able to figure out what letters is in genotypes of the parents. Heterozygous that means it always have one of each letter. A same trait can use for the same letter (capital & lowercase). Heterozygous that means one of each letter like where T is tall and t is short. The only two pea plants had to be short and has 2 lowercase. It cross ends up for the same.

__ Step 2: To write down your own Cross Mating and __ Write the genotypes of the parents in the form of letters (ex:Tt &tt).

__Step 3:__ Draw p-Square.

__Step 4:__ Split them on the left side, and outside of the rows of the p-square. The big T will be each of the boxes on the top row and The lowercase t would be two boxes is in the bottom Row. Two letters on the Second parent's genotype to split them up and place them on above each two columns. It will be two boxes directly and A letters that represent it.

__Step 5:__ One from the left, One from the top, One from the left, One from the top, One from the left, One from the top, One from the left, One from the top.

__Step 6:__ The results of Genotypes and Phenotypes that Dominant means Capitalize and Recessive means lowercase. The Genotype that all Capitalize on each boxes means to get 100% percent for Homozygous Dominant. The 50% percent for it has Tall and Short that means heterozygous. The lowercase letter that means homozygous reccessive to get 25% percent.

__Step 7:__ We are good to understanding it, conference, and Any questions.

Because, The Human Migrations that people lived in from one country to another. A Surname that it is located in your last name on the map, Top on 25 surnames in each states in 2000, and origins of surnames.
