What would happen in the wild to birds with beaks that have slight adaptations increasing their fitness for a particular environment?
they would survive and reproduce
This loss of genetic variation occurs when an established population has a drastic decrease in numbers.
bottleneck effect
An uppercase (capital) letter by itself is used to represent a
dominant allele.
An inherited characteristic that increases an organism’s ability to survive and reproduce in its environment is called a(n)

When a red-flowered plant is crossed with a white-flowered plant and the offspring has pink flower, it is an example of
incomplete dominance

What does evolution mean, in terms of genetics?
a change in the allele frequencies over time
