The Punnett square is used to predict the possible genotypes and phenotype probabilities of offspring from a genetic cross by combining the parental gametes.
Example: crossing Tt × Tt (T = dominant tall, t = recessive short) gives a 1:2:1 genotype ratio (TT:Tt:tt) and a 3:1 phenotype ratio (tall:short).
Note: it assumes simple Mendelian inheritance (independent assortment, no linkage or other complications).
