Punnett Squares are used by geneticists to determine the likely genotypes of the offspring of two parents.

True or False?

That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.
Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination. See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.

Punnett Squares are used in genetics to predict the likely genotypes of offspring from two parents. They show possible allele combinations by organizing parental alleles in a grid format. This tool is crucial for understanding inheritance patterns and genetic variation.
