How could genetic drift explain differences in the genotype frequencies among the caucasian and aborigine populations?

Biology
1 answer:
Novay_Z [31]3 years ago
7 0

Genetic drift occurs when there is no random mating across a population. This causes a change in allelic frequency due to a random sampling of the population.

As the aboriginal population explored the earth,  a small part of the population became geographically isolated either due to continental drift and climate changes. As the isolated population grew bigger, they established their own gene pool. This resulted a change in genotypic frequencies from that of the aboriginal population.

Where does the energy for human metabolism come from
SVETLANKA909090 [29]

Answer:

From food

Explanation:

Food energy is a chemical energy used by humans through the process of cellular respiration. Food contain macromolecules such as lipids, proteins, carbohydrates, water, vitamins, and minerals that are necessary for the human metabolism and they are broken down and used by the series of metabolic steps (glycolysis, Krebs  cycle, electront transport chain and oxidative phosphorilation). Digested macromolecules should be used either as a source of energy or as building blocks for the cell.

At the end of catabolic processes within an organism food energy is transformed into energy usable by the cell-ATP.

In gel electrophoresis, how are the dna samples added to the wells?.
jenyasd209 [6]

DNA samples are added into wells with the help of electric current.

<h3>How dna samples added to the wells?</h3>

DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

So we can conclude that DNA samples are added into wells with the help of electric current.
