These letters represent gene combinations. If the male has two genes for one trait: AA, and the female has two genes for the same trait:aa, the offspring will get one (A) and one (a) from each and together the offspring will have Aa for its' trait.
This Punnett square helps to show what the crosses will be and in what ratio.
The allelic make-up of the parents goes on the outside of the boxes, the female gametes go across the top and the male gametes go down the left side. The haploid gametes of the parents go on the outside of the Punnett square. The results that you get when you cross-multiply the male and female gametes of the parents are the diploid offspring, which goes inside the boxes.
Alleles of a certain gene or multiple genes. For example, you might use the letter 'b' to represent coat colour in guinea pigs. The capital B would represent the dominant allele, and the lowercase b would represent the recessive allele.
Each grid box in a Punnett Square represents an example of the genotype of a potential offspring. One allele from each parent is placed in the box, forming unique gene combinations.

The probability of the genes
Each box represents a possible offspring.
A punnet square uses letters to represent dominant and recessive alleles.

Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
Capital letters on Punnett Squares represent dominant genes, while lowercase letters represent recessive genes. For example, if the trait "T" is a tall gene and the trait "t" is a short gene. When you get your results (if both parents are heterozygous for tallness, Tt) you get four possible results, 1 TT (homozygous tall), 2 Tt (twice, heterozygous tall Tt), and 1 tt (homozygous short). If there is a dominant gene there, that gene will be displayed. Only if there are two recessive genes will the recessive trait be displayed.
A punnet square uses letters to represent dominant and recessive alleles.
capital letters are dominant traits. Lower case letters are recessive traits.
A genotypic combination
A dominant gene
Two letters which represent that parent's traits. They might be called alleles (its been a while).
A capital letter in a Punnet Square represents a dominate allele.

What do letters on the inside of the pungent square stand gor
a+b+c=4 a^2+b^2+c^2=10 a^3+b^3+c^3=22 Hope that helps. :)
A banana is a good example of a punnet square since it has absolutely nothing to do with a punnet square.
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
