Introduction To Genetics (Bio B)

Which statement best describes an understanding of genetics that would be missing without the work of Mendel?

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

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?

Why did Gregor Mendel use peas in his experiments?

Gregor Mendel's research formed the basis of the field of

Some people have freckles, and some people do not have freckles. If a child has freckles, at least one parent has freckles. However, the child may have a sibling that does not have freckles. Which statement best describes the presence of freckles?

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?

What controls traits and inheritance?

Which statement describes Mendel's hypotheses regarding gametes?

Tall pea plants are dominant over short pea plants. 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?
