What are punnett squares used for? a. determining the dna sequence of a given gene b. testing for the presence of the recessive allele c. predicting the result of genetic crosses between organisms of known genotypes d. identifying the gene locus where allelic variations are possible e. more than one of the above?

The answer I believe is E because the Punnett square is a square diagram that is used to predict an outcome of a particular cross or breeding experiment. The diagram is used by biologists to determine the probability of an offspring having a particular genotype. Punnett squares are also used to show all of the combinations of alleles that might result from a cross and the likelihood that each might occur.
