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?
Which has the most control of traits and inheritance?
What is a gene?
What alternate form of genes do nucleic acids have that allows them to offer variability?
Which statement best describes an understanding of genetics that would be missing without the work of Mendel?
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?
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?
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 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?
