Answer:
12:3:1
Explanation:
<em>The typical F2 ratio in cases of dominant epistasis is 12:3:1.</em>
<u>The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus</u>. There are different types of epistasis depending on the type of alleles that are interacting. These include:
- Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.
- Other types of epistasis include <em>recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).</em>
An increase in human population negatively impacts the water resources. There is only a small amount of clean and drinkable water on Earth. If more people are on Earth, more of this water will be used by the population. An increase of people also means that more fossil fuel will be used.
<h3>How does human population impact water resources?</h3>
Population growth especially will limit the amount of water available per person, because an increase in per capita water consumption driven by development will intensify water demand, straining the local water supply.

Answer:
balanced
Explanation:
Equal forces are being applied from opposite sides, so they cancel out. Think about pushing on both sides with the same amount of pressure on both sides. Its not gonna move. Hope I could help!
