Answer:

The correct answer is option b. "The genes share a specific combination of control elements".

Explanation:

Human eye color is an example of a trait that is controlled under the influence of multiple genes (polygenic). Human eye color is mainly determined by the amount of melanin that is present in the front part of the iris, which it is controlled by up to 16 genes. Among the different genes, the ones that mainly influence eye color are: OCA2 and HERC2. These two genes share a specific combination of control elements, for instance, a regulatory element of HERC2 gene inhibits OCA2 expression as well.

Lynna [10]
<span>This behavior is an example of B. overproduction. The frog lays thousands of eggs, which is much more than it needs, or would need in perfect conditions. However, most of those eggs doesn't survive, and little frogs are never born in that case. This is why it has to have a lot of eggs so as to ensure that a decent number of offspring survives so as to continue the species.</span>

In a sample of double-stranded DNA, 10 percent of the nitrogenous bases are guanine (G). What percentage of the nitrogenous base
DanielleElmas [232]

Answer:

40%

Explanation:

Remember that guanine always pairs with cytosine, and thymine always pairs with adenine. That means that any time there is a guanine, there is always a cytosine.

If there are 10% guanines, then there are 10% cytosines. That means the total of guanines and cytosines is 20%.

The other 2 bases (thymine and adenine) have to make up the rest of the bases. That means they have to make up 100-20 = 80%.

Again, there will be equal amounts of thymine and adenine, so 80%/2 = 40%.
