On the left side of the square put the T as the first row, t as the second row. On the top put P as the first column and p as the second column.
In the squares the first square is TP and next one is Tp. Lower left is tP and lower right is tp.
This means the possible outcomes are Thorny pink, thorny blue, smooth pink and smooth blue.
This is from parents that are heterogeneous. If parents were both homogeneous dominant the rows and columns would both have capital letters and only capital letters inside the square.
What the Punnet square is trying to do is show all the possible combinations with two choices.

A punnett square looks like this. Lets say that you had 2 flowers, and you wanted to find the likelihood that their offspring would be purple. Purple is dominant over white. You have one pure purple plant, (PP), and one hybrid purple plant, (Pp). The big P stands for purple, and the little p stands for white. You take the PP and put it on the top, one P over each of the top squares. Then you take the Pp and put each p on one of the side squares. You take one letter from each part of the square, so your four possibilities would be PP, PP, Pp, and Pp. There is no way that the plant could be white.
The one that doesn't follow the pattern of a^2 - b^2.
The unit digit of the square of 81 will be 1.
Punnett squares demonstrate the percentage of traits that are passed on from one generation to the next. It shows the pairings of dominant and recessive genes and what percentage there is of the next generation having those particular traits.
Homozygous, heterozygous, dominant, recessive, co-dominant, incomplete dominant, alleles, multiple alleles, polygenic inheritance, test cross, Punnett squares, hybrids, carriers, ratios, percentages, locus.

punnett squares
The person who invented punnett squares and further studied Mendel's theories was named Reginald Punnett. Therefore the punnett square was named after him.
They are a part of genetics.

Gregor Mendel created/used punnett squares in order to predict the genotypes and phenotypes of offspring.
Homozygous means "same" so a homozygous recessive trait would be a same [with parents] trait that is not the stronger trait which is dominant. Dominant is stronger showing trait, recessive is weaker trait. If you are dealing with Punnett squares then tt is homozygous recessive and TT is homozygous dominant. Hope this helped...
Punnett squares
The tool used to visualize all of the possible combinations of alleles from parents to offspring is called a punnett square.
