Directions
Complete the questions below. These questions are intended to enhance critical-thinking skills by applying knowledge obtained from the lab activities into real-world challenges.
⢠If ratios or probabilities are asked for, your answer should involve fractions or a percent.
⢠If phenotypes are asked for, describe the traits.
⢠If genotypes are asked for, describe alleles using the letter symbols like Aa (e.g., a genotypic ratio might be: 1/3 AA, 1/3 Aa, 1/3 aa, and a phenotypic ratio might be: 3 short, 1 tall or 3:1).
1. Solve for the type of inheritance in punnet square form and explain the rationale of your choice:
a. Mice: red-eyed mouse X white-eyed mouse gives F1: all red-eyed
b. Flowers: blue-flowered plant X white-flowered plant gives F1: all pale-blue-flowered
c. Flowers: pale-blue F1 X pale-blue F1 gives F2:
i. 27 blue
ii. 49 pale-blue
iii. 24 white
d. Blood Type: cross 1: type A blood X type B gives F1:
i. 2 type A blood
ii. 3 type AB blood
iii. 1 type B blood
iv. 2 type O blood
