In trout, Gene A affects body color and yellow color (allele a) is recessive to red. In a particular river system you find that

hjlf

Answer:

The frequency of the dominant A allele is 0,4 or 40%.

Explanation:

In this population, we have:

- "A" red body color Dominant

- "a" yellow doy color Recessive

So, individuals AA and Aa will be red and trouts aa will be yellow. In this case, 64% of the fish are red, so they are AA or Aa.

If the population is in Hardy-Weinberg equilibrium the following will be true:

$p^{2}+2pq+q^{2}=1$

Where:

$p^{2}=$ frequency of AA

$2pq=$ frequency of Aa

$q^{2}=$ frequency of aa

It is known that 64% of population is red, in other words:

$p^{2}+2pq=0,64$

Or AA+Aa=0,64

So, it is possible to find the value of $q^{2}$ (aa):

$p^{2}+2pq+q^{2}=1$

$(0,64)+q^{2}=1$

$q^{2}=1-0,64$ $q^{2}=0,36$

Now, there are two alleles in this population, therefore their frequencies will be:

$p+q=1$

So, from $q^{2}$ it is possible to find q and p:

$q=\sqrt{q^{2} }$

$q=\sqrt{0,36}$

$q=0,6$

And:

$p+q=1\\p=1-q\\p=1-0,6\\p=0,4$

How is a hummingbird getting nectar from a flower an example of mutualism?

horrorfan [7]

Mutualism is when both sides benefit. The hummingbird gets nectar and the flower is benefited because the hummingbird that has been to other flowers carry pollen on its body which spread the flower when it sucks its nectar, therefore pollinating the flower in the process.
