Punnet square is a chart use to chart or put the genotypes of offsprings. It is used usually in science to find what the offspring will look like or have what traits from the parents. It is a square with four mini squares inside. In the mini square is were you chart the offsprings' genotype.
To do it you make the chart. First with a square and then a lower case t in the middle to make the four mini squares. Then put in the parents genotype for the trait you are looking for. Then do columns and rows. Next look at the first letter of the genotype in the first row and columns or columns and rows. For example, the genotype of the father is big G little g (Gg) which can be placed on the top of the punnet square or the left hand side of the square. Next the genotype of the mother is little g little g (gg), which can be paste in the extra spot of the father's genotype.
As you can see the first row and column is big G little g, or Gg because it came from the first letter of each parents. Now that will be placed on the first mini square. Next the mother's little g lines up with the little g on the right hand side of the father's. The second mini square is little g little g, (gg). Then the next row moving downward to the next letter is little g of the mother(Notice: only move if you did rows to columns). Also move to the second letter in the columns if you start with columns to rows if not leave it. Now do as the same as before, little g to big G. Of couse, sometimes it is written gG, but the correct way to write it is Gg, just switch it. Now put that in the third punnet square. Next the mothers second little g lines up with the second little g of the father. It is little g little g on the fourth one. Now your done!
Solving a punnet square can be pretty complicated and confusing if you don't pay attention or listen closely, so pay attention! That was what I did so solving punnet square wasn't very hard for me.
