  2. p. 318 A.Q. 1ab, 2ab, 3ab 1a. What is probability? 1a. Probability is the likelihood that a particular event will occur. T t 1b. How are Punnett squares used to predict the outcomes of genetic crosses? 1b. Punnett squares are used to show all of the combinations of alleles that might result from a cross and the likelihood that each might occur. t Tt tt t Tt tt

  3. p. 318 A.Q. 1ab, 2ab, 3ab 2a. What is independent assortment? 2a. Independent assortment is the concept that during gamete formation, pairs of alleles for a gene segregate, or separate, independently of each other. 2b. An F1 plant that is homozygous for shortness is crossed with a heterozygous F1 plant. What is the probability that a seed from the cross will produce a tall plant? Use a Punnett square to explain your answer and to compare the probable genetic variations in the F2 plants. 2b. The probability is 50%. T t t Tt tt t Tt tt

  4. p. 318 A.Q. 1ab, 2ab, 3ab 3a. How did Gregor Mendel contribute to our understanding of inherited traits? 3a. The patterns of inheritance Mendel observed form the basis of modern genetics. 3b. Why is the fruit fly an ideal organism for genetic research? 3b. The fruit fly is an ideal organism for genetic research because fruit flies are small, easy to keep in the laboratory, and produce large numbers of offspring in a short period of time.
