Answer:
Population genetics
Explanation:
Population genetics refers to the study of distribution of genetic traits and the allelic changes occurring in a population that is variations in the alleles and genotypes.
A population that is freely interbreeding has a collection of genes and alleles called a gene pool of the specific population.
Each member will receives alleles from the gene pool( from its parent) and passes it to other members (offspring)
It illustrates the cycling of matter, just like in a natural ecosystem.
Option D.
<h3><u>Explanation:</u></h3>
The natural stable ecosystem is defined as the ecosystem which has the members doing their part of job and each and every member contribute to the stability of the ecosystem by completing food chains.
Here in this bottle ecosystem the boy put the stones, rocks, water which gives proper nutrition to the growing plants and animals which are also introduced by the boy. The plants produce oxygen and consume carbon dioxide whereas the animals consume oxygen and produce carbon dioxide. Thus the cycle is maintained and stability is achieved.

Explanation:
<span>In order for this gene to be useful in differentiating different salmon breeds, the specific coi gene sequences must be either found or absent in all individuals of a breed, be about the same among individual breeds unless a mutation is found in an individual, and different from the coi gene sequences of other breeds. If the coi gene is found to be the same between two or more salmon breeds, then another gene will be necessary in order to differentiate between breeds.</span>
