Answer;
-Allele frequency change
In single-gene traits, natural selection can lead to allele frequency change.
Explanation;
-Allele frequencies can change over time within a single population, and frequently differ between populations. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.
-Random forces lead to genetic drift. Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.
Answer:
Explanation:
Feasibilities studies-it analyzes a project to see if its possible technically, legally and financially.
Technical feasibility tells about if all the tools and equipment are available for the construction while financial talks of the financial ability.
Survey- They area of land where the offshore will be constructed will be surveyed and other surrounding environment to know the existing feature in such area of land that can pose threat to the offshore being constructed. This includes lives and houses built around the off shore to know how save their live is when the off shore built in such place.
