This can be solved either by using a Punnet Square or you can use the formula (n(n+1))/2, where n is the number of alleles. However, using either method will give you the number of possible genotypes regardless if it's homozygous or heterozygous. If we use the second formula, that will give you 10 possible genotypes. Since you only want to know the number of heterozygous genotypes, you should subtract the number of possible homozygous genotypes. In this case, there are four. That is (A1,A1), (A2,A2), (A3,A3), and (A4,A4). Knowing this, you'd be able to figure out that there are six heterozygous genotypes.
(A1,A2), (A2,A3), (A3,A4), (A1,A4), (A1,A3), (A2,A4)

Answer:
<em>decreased variation in the shades of red over time because no form of the trait is advantageous</em>
Explanation:
Natural selection tends to favor those organisms which are better adapted to live in an environment. These organisms are able to survive and pass on their characteristics to their offsprings.
The red colour of the male cardinal's was selected by natural selection and hence this colour was abundant. If the females choose some other criteria for mating with males, then natural selection will no longer favor the red colour and hence there will be a decrease in the variations of red coloiur.
Answer: Cochlea
Explanation: The inner ear contains a group of interconnected, fluid-filled chambers. The snail-shaped chamber, called the cochlea, plays a role in hearing. Sound vibrations from the bones of the middle ear are transferred to the fluids of the cochlea
