front 1 What does the notation Rr mean to geneticists? | back 1 heterozygous alleles |
front 2 Two plants are heterozygous for seed shape and have round seeds. If the two plants are crossed, what is the probability that the offspring will have wrinkled seeds? | back 2 25 percent |
front 3 When Mendel crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp), what were the flower colors of the resulting offspring? | back 3 100 percent purple |
front 4 A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr. What is the probability that the offspring will have wrinkled seeds? | back 4 50 percent |
front 5 Parents that are heterozygous for having freckles (dominant) are crossed. Which correctly describes their offspring? | back 5 Seventy-five percent have freckles. |
front 6 What is a gene ? | back 6 a segment of DNA that is the basic unit of heredity |
front 7 Why did Mendel study pea plants? | back 7 They reproduce sexually and have many traits that are easy to observe. |
front 8 Which of Mendel's laws or principles states that gametes carry one allele for each trait? | back 8 law of segregation |
front 9 Which statement summarizes the law of segregation? | back 9 Gametes carry one allele for each trait. |
front 10 The diagram represents one of Mendel’s laws or principles of inheritance. Which law or principle shown in the diagram is represented by the F2 generation having one gene from each parent? | back 10 Segregation |
front 11 Which of Mendel's laws or principles explains that traits are passed from parents to offspring individually instead of as pairs, groups, or sets? | back 11 The law of independent assortment |
front 12 Each kernel of corn on a single ear can inherit a different set of alleles from those inherited by other kernels. This characteristic makes corn a useful example of which law or principle? | back 12 Taw of independent assortment |
front 13 Which type of scientific statement is defined as "a possible explanation or answer to a scientific question that is based on prior knowledge or research and is testable"? | back 13 Hypothesis |
front 14 Which type of scientific statement is defined as a statement of fact that is generally accepted to be true and universal because it has always been observed to be true? | back 14 Law |
front 15 The concept of evolution by way of natural selection is a central tenet in biology that has been tested in numerous ways by many scientists. Evolution by way of natural selection is most likely which type of concept? | back 15 an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation |
front 16 What can be known about Mendel’s five-part hypothesis? | back 16 It is an answer to a scientific question and is based mostly on his research. |
