A gene is a small segment of DNA that contains the information required in order to build a protein!
False
Many people can live in one area, but have close to no one living somewhere else.
Mutation is the only evolutionary mechanism that does little to change allele frequencies.
The allele would be called codominant
When a dominant and recessive allele exist in an organism, only the dominant allele will be expressed. Dominant allele always mask the recessive because the gene code a protein while recessive gene doesn't. When both gene code a protein, they will be codominant and both gene will be expressed. The result could be a mixed effect. In this case, the purple is mixed color of red and blue.
