<span>How can a mutation in a DNA base sequence cause a change in a trait?</span>
The answer should be 3
Explanation:
One plant will for sure have red leaves, while the other two have a probability of having red and yellow leaves, and one plant will only have yellow leaves.
Yellow: Y
Red: y
Two plants: Yy
Although the Red is recessive so it's a smaller chance of it overpowering the yellow, the answer might also be 1.
