Which statement best describes why Punnett squares are useful? Punnett squares are used to predict the most likely allele combinations of the parents in a cross.

Punnett squares are used to predict how dominant alleles are inherited.

Punnett squares are used to predict all possible allele combinations and their frequencies in offspring.

Punnett squares are used to predict how recessive alleles are inherited.

The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype. The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. These tables can be used to examine the genotypic outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents. The Punnett Square is a visual

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

the answer is b.) hydrogen bonds between bases.
