Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds?

Which statement describes Mendel’s hypotheses regarding gametes?

What is a gene?

In pea plants, tall plant height is dominant over short plant height. If there are 200 short plants in the F2 generation from a cross that followed Mendel’s methods, about how many plants will be tall in that generation?

Which is the best example of a hypothesis leading to new experimental methods?

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.In which squares should the phrase “Green pods” appear?

During an experiment, a scientist crosses a pea plant that has purple flowers with a pea plant that has white flowers. The plants that result from this cross in the F1 generation have both purple and white flowers. What can the scientist conclude?

Scientists often use fruit flies as a method to test hypotheses about human genes. Why are fruit flies advantageous in the study of human inheritance?
