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>
Homeostasis it is an organism's ability to keep a constant internal environment.
Answer:
As the name suggests, proteases will be the enzymes which will catalyze the reactions of proteolysis. Proteolysis can be described as the process of breaking proteins into amino acids and simple peptide bonds.
DNases will catalyze the reactions for breaking down or degrading DNA. The DNase does this by breaking the phosphodiester bonds present in the backbone of the DNA.
RNases will be the enzymes which will catalyze the breaking of RNA molecules.
Answer:
An example of macroevolution is the evolution of a new species. One mechanism that drives evolution is natural selection, which is a process that increases the frequency of advantageous alleles in a population. Natural selection results in organisms that are more likely to survive and reproduce.

2. Number 10.
I'm pretty sure it's that, I just did something related to that.
