Model: Use the Punnett squares below to model each parent combination. After filling in each Punnett square, predict the percentages of black and white offspring. Parent 1: Heterozygous black (Ff) Parent 2: Heterozygous black (Ff) Predicted % black offspring: Predicted % white offspring: Parent 1: Heterozygous black (Ff) Parent 2: Homozygous white (ff) Predicted % black offspring: Predicted % white offspring:

cross 1: 75% black    25% white    

cross 2: 50% black  50% white offspring    

Explanation:

Cross 1

Heterozygous black  x    heterozygous black

            F        f  

F         FF       Ff

f          Ff        ff  

75% black    25% white    

Cross 2

Heterozygous black x   homozygous white

          F         f

f        Ff        ff

f        Ff        ff

50% black  50% white offspring
