Primavera Biology B Unit 1: Genetics Questions and Answers 100% Pass CHECKPOINT 01 ✔✔ Some people have dimples; other people do not. Having dimples is dominant over not having dimples. If the allele for having dimples is represented with the letter D, what allele combinations can result in having dimples? ✔✔DD, Dd Which statement is true about model organisms? ✔✔They help scientists understand biological processes. A pea plant that is tall has a dominant trait. Which statements are true about the genotype/phenotype relationship of the plant? Select all that apply. ✔✔When the phenotype is tall, the genotype can either be TT or Tt. The genotype Tt always results in a phenotype that is ta ll. What statement would be true according to the theory of blending inheritance? ✔✔The offspring of a tall parent plant and a short parent plant will all have a height in the middle. Mendel crossed a tall pea plant with a short pea plant. All the offspr ing in the first generation were tall pea plants. How did Mendel explain why all the offspring were tall pea plants? ✔✔Two factors affect the height trait of pea plants. One of the factors is dominant over the other. Read the statement: When Mendel crosse d a purple -flowered pea plant with a white -flowered pea plant, the offspring were always X. When Mendel crossed the offspring with each other, the distribution was about Y purple and Z white. The more experiments Mendel did with pea plants, the closer they approached these percentages. Which option correctly replaces X, Y, and Z in the statement? ✔✔X: purple Y: 75% Z: 25%
