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?
They can self-pollinate
alleles
Peas have characteristics that have two forms
The plants in the P generation were not true-breeding
develop new methods to test the hypothesis
Some alleles are dominant, and some are recessive
A section of DNA that codes for a specific trait
The offspring will inherit one gene from each parent
Nucleic acids offer variability because they contain alternate forms of genes called ___________.

A scientist wants to examine a genetic disease in humans. The scientist hypothesizes that the disease can be treated by using gene therapy. Humans take a long time to reproduce and develop, so the scientist will have to .....
