The letters on the outside of the Punnett square stand for the alleles of each parent. One parent's alleles are written across the top of the square, and the other parent's alleles are written along the left side of the square. The pairs of alleles inside the square represent all the possible genotypes for their offspring.
a pair of recessive genes
well it depends on the letters that you are given, recessive alleles are ALWAYS lower case.An example answer would be: ss, where s would represent the recessive allele.
Dominant alleles are written in upper case (i.e, 'A'), while recessive alleles are lower case (i.e, 'a')
Dominant AllelesUsually dominant alleles are represented as capital letters, whereas recessive alleles are represented by the lowercase letter. Presumably, the capital letter will help you remember which is which -- dominant correlates with capital. However, you can assign alleles whatever letter, number, or symbol you want - as long as it produces the same genotype and phenotype ratio. The symbols/letters that are created for Punnett Squares or another process are purely for organizational purposes. Think of it this way: if you have a heterozygous organism that mates with a homozygous organism of the same species, how will you find the genotypes and phenotypes of the offspring? Well, you certainly aren't going to figure it out abstractly in your head. Assigning letters to dominant/recessive alleles is just to keep track of where the alleles are possibly going and the results. If you want the dominant allele to be "R" and the recessive allele to be "r", then that's perfectly acceptable. And if you want to represent the dominant allele with a Batman symbol and the recessive allele with a radioactive symbol, then that's fine too... as long as you know that the Batman symbol represents the dominant allele and the radioactive allele the recessive.
true
Geneticists use probability to predict possible genotypes and phenotypes
A punnet square uses letters to represent dominant and recessive alleles.
capital letters, such as PP equals two dominant alleles, pp equals two recessive alleles.

The letters represent the alleles, or variations, of a given trait. So for example T might represent tall and t represents short. The capital letter always corresponds to the dominant trait and the lowercase letter corresponds to the recessive trait.
Genotypes are written with two letters to represent the two alleles inherited from each parent. The letters represent different forms of a gene, with one letter from the mother and one from the father, to show the genetic composition of an individual for a particular trait.

Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.

Two letters which represent that parent's traits. They might be called alleles (its been a while).
