Master Punnett squares for genetics! Predict offspring traits and probability.

Complete the Punnett Square and answer the questions that follow. In rabbits, black fur is dominant to white fur. If you cross a BB male with a Bb female, what are the possibly genotypes and phenotypes of the offspring? Punnett Square B B B BB BB b Bb Bb What is the percent chance the offspring rabbit will be black? 0% 25% 50% 100% What is the percent chance the offspring rabbit will be white? 0% 25% 50% 75% Create a Punnett Square and answer the questions that follow. In cabbage butterflies, White wings are dominant to yellow wings. If a Ww butterfly is crossed with a ww butterfly, what are the possible genotypes and phenotypes of the offspring and the percent chance for each. Punnett Square W w w Ww ww w Ww ww What is the percent chance the offspring will have white wings? 25% 50% 75% 100% What is the percent chance the offspring will have yellow wings? 0% 25% 50% 75% Create a Punnett Square for each cross given to determine the phenotype and genotype. A tall plant (TT) is crossed with a tall plant (TT) Punnett Square T T T TT TT T TT TT Based on the Punnett square above, identify the genotype and phenotype. Genotype: 4 TT; 0 Aa; 0aaPhenotype: 4 tall plants; 0 short plants For each of the genotypes below, determine what the phenotype would be. Purple flowers are dominant to white flowers.PP: purplePp: purplepp: white Determine whether each of the following is homozygous dominant, heterozygous or homozygous recessive. Homozygous Dominant AA TT Heterozygous Ff Pp Ll Homozygous Recessive gg ss For each of the genotypes below, determine what the phenotype would be. Bobtails in cats are recessive. Normal tails are dominant.Tt: normalTt: normaltt: bobtails
