GENETIC VARIATION

Question 1

refers to the diversity within a species.

Answer 1

Genetic Diversity

Question 2

refers to the diversity within a species.

Answer 2

Genetic Diversity

Question 3

The greater the genetic diversity, the higher is the chance of a long-ferm survival.

Answer 3

Genetic Diversity

Question 4

The differences between the genes of each individual and the differences between genes of the different populations are termed as

Answer 4

Genetic Variation

Question 5

The number of times at which the common gene appears in everyone within a population is called

Answer 5

Gene/Genetic Frequency

Question 6

refers to how common a specific gene is in a group of specie within a specific area.

Answer 6

gene frequency

Question 7

Any change in the gene frequency of a species or population is

Answer 7

Evolution

Question 8

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.

Answer 8

Evolution

Question 9

is a change in the
genetic composition of a population over successive generations.

Answer 9

Evolution

Question 10

This is also termed as selective breeding.

Answer 10

Artificial Selection

Question 11

It is the process which is also known as “Survival of the Fittest.”

Answer 11

Natural Selection

Question 12

is a process in nature through which living organisms adapt and change in response to an environmental condition.

Answer 12

natural selection

Question 13

involves an organism looking like another species,

Answer 13

mimicry

Question 14

involves an organism blending into its environment.

Answer 14

camouflage

Question 15

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.

Answer 15

Gene Flow/Migration

Question 16

is a mechanism that may bring change to the gene frequency in a population because of “chance” events.

Answer 16

Genetic Drift

Question 17

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.

Answer 17

Genetic drift

Question 18

regular cell

Answer 18

somatic mutation

Question 19

regular cell

Answer 19

somatic mutation

Question 20

sex cells

Answer 20

germline mutation

Question 21

It occurs when some species choose a partner with preferred characteristics.

Answer 21

Non-Random Mating

Question 22

is life’s way of bringing variety in similarity. It occurs during meiosis, the cell replication process used for reproduction.

Answer 22

recombination

Question 23

is a change in the DNA sequence of an organism.

Answer 23

mutation

Question 24

can be caused by errors in DNA replication, exposure to mutagens, or viral infections.

Answer 24

mutation

Question 25

is when-mutation takes place in the somatic cells or regular cells of the organisms; hence will not be replicated during meiosis.

Answer 25

Somatic Mutation

Question 26

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

Answer 26

germlin mutation
