Answer;
a segment of chromosomal DNA
Explanation;
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.
It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.
<span>There are two major theories that will explain on research on colour vision. They are 1. the trichromatic theory also known as the Young-Helmholtz theory 2. opponent-process theory. These two theories explain processes that operate at different levels of the visual system.</span>
The answer is:
Community Diversity.
Reason Why: Here is an example, say you have 2 communities, community 1 is A, and community 2 is B, Communities A and B contain 5 tree species, However because community B has greater species evenness it has greater species diversity.
Community A is dominated by one of its 5 species and so has lower species diversity than.....community B, which has the same 5 species but in equal proportion.
Richness- Number of Species
Evenness-Relative abundance.
