Natural selection act directly upon <u>Alleles</u>
Explanation:
Genes, such as that of fur color, have many variants called alleles. Natural selection act on the alleles and chooses the best fit for an environment and eliminates the disadvantageous ones from the population over generations. Mutations are a rare occurrence that increases the number of allelic variants of a genes on which natural selection can act upon.
Why is it important: It helps us adapt to our environments and become more stable in our environments.
What is it: The change of traits that can lead to better adaptation in our ecosystems.
(I'm not completely sure, but if you have zero clues I recommend just trying this if you get no other answer. Good luck!)
A is your answer. it cant be B because H doesn't equal 2 on both sides.it cant be C because S doesn't equal 3 on both sides of the equation . It also cant be D because Au doesn't equal 3 on the first part of the equation so your best answer is A. Hope this helps!!!!
The correct answer is C incomplete dominance, because the pink flowers represent a third phenotype. Incomplete dominance<span> is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over the other allele which results in the formation of a third phenotype, which in this case is the pink flowers:)</span>
