<reasoning>

Analyze expression in heterozygotes

In a heterozygous individual (having two different alleles for a gene, such as \(Aa\)), the allele that is masked and not expressed in the phenotype is the recessive allele. Therefore, the recessive allele is not expressed.

Analyze active expression in heterozygotes

Conversely, in a heterozygous individual, the allele that is fully expressed and determines the organism's appearance is the dominant allele.

Identify the genetic diagram tool

A Punnett square is a graphical representation used to calculate and predict the probability of different genotypes and phenotypes in the offspring of two parents.
