Punnett Square SCIENCE · 7TH GRADE Name Date Read the passage, then answer the questions below. A Punnett square predicts the possible gene combinations of offspring from two parents. The alleles from one parent are written along the top and those from the other down the side; each box shows one combination the offspring could inherit. For a cross between two parents each carrying one dominant and one recessive allele, the square gives a 3 to 1 ratio of dominant to recessive appearance. The square shows probabilities, not certainties — a 1 in 4 chance does not mean exactly one in every four offspring. Questions: 1 What goes along the top and side of the square? 2 What ratio comes from crossing two parents with one dominant and one recessive allele? 3 Why is a 1 in 4 result not a guarantee? littleactivity.com 7th Grade · Science
