1. How would you write the alleles for a plant that is purebred tall?
2. How would you write the alleles for the offspring of a cross between a purebred tall plant and a purebred short pea plant? 3. What term did Mendel use for an individual with one dominant allele and one recessive allele? Today in class we discussed the concepts in chapter 10 lesson 2 on probability and genetics. Students got to toss a coin 20 times and record the number of heads versus tails, and compared that to their prediction. Students also participated in a group activity where they used coins to model Mendel’s cross between two Tt pea plants. (In pea plants, T is the dominant allele for tall stem height. The recessive allele for short stem height is t. ) Students 1. Placed a small piece of masking tape on each side of two coins. 2. Wrote a T (for tall) on one side of each coin anda t (for short) on the other side. 3. Tossed both coins together 20 times. Recorded the letter combinations that they obtained from each cross. Each cross represented one offspring. At the end of the activity we answered the following questions 1. Based on your results, how many of the offspring would be tall plants? How many would be short? 2. Convert your results to percentages. How do they compare to the results Mendel obtained? Students are expected to read chapter 10 lesson 1 and complete the figure questions.
