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.
There are three ways in which exogenous dna can be
introduced into a bacterial genome. These are; transduction, transformation and
conjugation. Transduction is the introduction of exogenous material into bacteria
by viruses; conjugation is exchange of genetic material between bacteria sexual
through reproduction; while transformation
is uptake of exogenous dna by bacteria, from its surrounding, through the
bacterial membrane.
