The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.
<h3>What is a recessive phenotype?</h3>
A recessive phenotype is a phenotype which expresses the recessive trait of a gene.
The recessive phenotype is always h0m0zygous for that triat to be expressed.
In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:
where;
- p^2 is the h0m0zygous dominant phenotype frequency
- 2pq is the heterozygous phenotype frequency
- q^2 is the h0m0zygous recessive phenotype frequency
Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

Explanation:
Solar UV radiation. Australia experiences some of the highest levels of UV radiation in the world because we are close to the equator and have many clear, blue-sky days. The Earth's orbit also brings countries in the southern hemisphere (Australia included) closer to the sun in the summertime than countries in the northern hemisphere during summer.

Answer:
Hypotheis:
<em>If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...</em>
- <u>A- Pepsin</u>
- <u>B- Amylase </u>
- <u> C- thermophilic enzyme</u>
Explanation:
Enzymes are specialized proteins that function as biological catalysts- <u>they speed up chemical reactions.</u> As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.
Each enzyme provided has its own optimal temperature and pH values.
- Thermophilic enzymes are usually found in regions characterized by high temperatures. They show high thermostability, and do not become denatured at high temperatures- they thrive, and do not function well at lower temperatures.
- Amylase is a hydrolase digestive enzyme found in the mouth, that acts on polysaccharides like starch to break 1,4 glycosidic bonds between glucose molecules. It works best at a physiological (neutral) pH and temperatures (around 37°)
- Pepsin, another digestive enzyme, is a peptidase that breaks down proteins into peptide molecules. It is found in the stomach lining, where the pH is typically low i.e. acidic due to the hydrochloric acid in digestive juices.
Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.
