GENETIC VARIATION Flashcards
refers to the diversity within a species.
Genetic Diversity
refers to the diversity within a species.
Genetic Diversity
The greater the genetic diversity, the higher is the chance of a long-ferm survival.
Genetic Diversity
The differences between the genes of each individual and the differences between genes of the different populations are termed as
Genetic Variation
The number of times at which the common gene appears in everyone within a population is called
Gene/Genetic Frequency
refers to how common a specific gene is in a group of specie within a specific area.
gene frequency
Any change in the gene frequency of a species or population is
Evolution
is the change in the genetic materials of organisms, it is a change manifested in their traits. It is also a change that started deep within the cells of individuals, in their genes, in their DNA, in their chromosomes.
Evolution
is a change in the
genetic composition of a population over successive generations.
Evolution
This is also termed as selective breeding.
Artificial Selection
It is the process which is also known as “Survival of the Fittest.”
Natural Selection
is a process in nature through which living organisms adapt and change in response to an environmental condition.
natural selection
involves an organism looking like another species,
mimicry
involves an organism blending into its environment.
camouflage
This occurs when a group or individual specie migrated from one place to another affecting the gene pool of the place that they left and the place where they arrive.
Gene Flow/Migration
is a mechanism that may bring change to the gene frequency in a population because of “chance” events.
Genetic Drift
It is a result of an incident or accident which may have brought significant and palpable change to the gene frequency or common traits in a given population.
Genetic drift
regular cell
somatic mutation
regular cell
somatic mutation
sex cells
germline mutation
It occurs when some species choose a partner with preferred characteristics.
Non-Random Mating
is life’s way of bringing variety in similarity. It occurs during meiosis, the cell replication process used for reproduction.
recombination
is a change in the DNA sequence of an organism.
mutation
can be caused by errors in DNA replication, exposure to mutagens, or viral infections.
mutation
is when-mutation takes place in the somatic cells or regular cells of the organisms; hence will not be replicated during meiosis.
Somatic Mutation
The Mutation on the sex cells or gametes is the only type of mutation that may affect the gene frequency of a population in the long run, this is called a
germlin mutation
