| The process of crossing two genetically different parent plants to produce offspring with traits of both parents. |
|
|
Term
| True/False: An example of horticulture is crossing one plant that grows quickly with another plant that is pest resistanct in the lab in order to produce offspring that both grow quickly and are pest resistant. |

Term
| How was Mendel able to manipulate pea plants to determine the mechanism of inheritance? |
|
Definition
| Pea flower pollen is contained in the anther and can be removed from the plant and used to fertilize another flower's ovules contained in the carpel. |

Term
| Put the following events in Mendel's life in chronological order |
|
Definition
|
|
Term
| True/False: Mendel's work filled such a large void in the understanding of genetics that it was no wonder it was hailed as a masterpiece when it was published in 1866. |
|
Definition
|
|
Term
| Which of the following sums up Josef Kohleuter's main contribution to the field of genetics? |
|
Definition
| He determined that both the male and female equally contribute to the appearance of traits in the offspring |
|
|
Term
| What is the best explanation as to why the theory of blending inheritance was abandoned? |
|
Definition
| It could not explain how variation in individuals was maintained over time. |
|
|

|
Definition
yellow male x green female
green male x yellow female |
|
|
Term
| Which one of the following is NOT one of the reasons that Mendel succeeded in determining the principles of inheritance? |
|
Definition
| He followed the inheritance pattern of many traits at the same time. |
|
|
Term
| A true breeding strain is one that? |
|
Definition
| produces offspring of the same variety when they self -pollinate |
|
|
Term
| To investigate patterns of inheritance Mendel looked at traits that |
|
Definition
| Were dichotomous in nature |
|
|
Term
| Mendel's primary experiments were conducted with |
|
Definition
|
|
Term
| Genetic studies in the 1900s often used the fruit fly as a model. Why did early studies of inheritance in the 1700s and 1800s use plants? |
|
Definition
|
|
Term
| Which one of the followin best describes a monohybrid cross? |
|
Definition
| Plants that differ in a single trait are cross-pollinated with each other. |
|
|
Term
| Which one of the following is not true of Mendel's parental cross? |
|
Definition
| His results indicated a ratio in the offspring of 3:1 |
|
|
Term
| Which of the following best describes a reciprocal cross? |
|
Definition
| Pollen from plant A is transferred to plant B and pollen from plant B is transferred to plant A |
|
|
Term
| Mendel used pea plants for his experiments for all of the following reasons except which of the following? |
|
Definition
| the characters varied over a continuous range of phenotypes |
|
|
Term
| Mendel hypothesized that traits did not blend together like paint but were particulate. At what part of the experiment could Mendel rule out the blending mode of inheritance? |
|
Definition
| At the F2, when the masked variety reappeared |
|
|
Term
| Mendel found that monohybrid crosses of true-breeding plants that differ in one trait always produced F1 offspring of the same variety. This variety of the trait is considered |
|
Definition
|
|
Term
| From his experimental results, Mendel developed a hypothesis that is now called the first law of segregation. Which of the following is not a part of this hypothesis? |
|
Definition
| Every organism gets two copies of a gene from each parent |
|
|
Term
| Which of the following is not true of Mendel’s mechanism of inheritance? |
|
Definition
| Heritable factors that are dominant are more likely to be passed on to the next generation. |
|
|
Term
| When a true breeding smooth-seeded pea plant is crossed with one that is a true breeding wrinkled seeded pea plant, why is a wrinkled-seeded offspring unlikely to result? |
|
Definition
| The smooth seeded gene masks the wrinkled seeded gene in the F1 generation |
|
|
Term
| In pea plants, plants with inflated pods are crossed with ones with constricted pods. All of the offspring are found to have inflated pods. If a cross is carried out among the offspring, what would be the expected ratio for the phenotypes of the F2 generation? |
|
Definition
| Three inflated to one constricted |
|
|
Term
| A pea plant with green pods is crossed with a pea plant with yellow pods. The F1 generation was all the same color. If 75% of the F2 generation have green pods and 25% have yellow pods, what conclusion can we make? |
|
Definition
| Both parent plants were true breeding |
|
|
Term

|
Definition
| The individual has smooth seeds |
