Populations of organisms

Why is artificial selection done?

Answer 8

To be pleasing to humans

Question 9

What are some draw backs to artificial selection?

Answer 9

Not necessarily good for the organism ex. Pure bred dogs have increased diseases - modern tomatoes have good size, shape and color but no flavor

Origin of species

Question 15

Life is a product of ?

Answer 15

Continuous change

Question 16

All species arose from a

Answer 16

single common ancestor

Question 17

Darwin developed theory of

Answer 17

Natural selection

Question 18

Organisms with the best traits for survival have a reproductive advantage;

Answer 18

This allows them to pass their traits on to their off spring

Question 19

What happened with cells in 1858

Answer 19

Deff if a cell was developed as well as theory

Question 20

What’s cell theory

Answer 20

All organisms are composed of cells- all cells arise from existing cells

Question 21

Population

Answer 21

A group of individuals of the same species living in the same area at the same time

Question 22

Trait-

Answer 22

A distinguishing feature I an organism

Question 23

Natural selection

Answer 23

The process by which individuals with certain heritable traits are better able to survive and reproduce, compared to other members of the population; process by which individuals are naturally selected

Question 24

What can nat selection occur?

Answer 24

The trait being selected for carie in the population, the trait is heritable and there is competition for survival

Question 25

What will happen to the offspring of individuals with a survival advantage?

Answer 25

They will have the same advantageous trait

Question 26

What increases from gen to gen?

Answer 26

Freq/percentage of those traits in the population

Question 27

Fitness

Answer 27

(Noun) ability to produce offspring relative to other individuals

Question 28

Adaptation (noun)

Answer 28

Heritable trait that increases fitness of a particular individual in a particular environment

Question 29

Adaptation (verb)

Answer 29

An evolutionary process; alters an organisms phenotype to enhance its ability to survive

Question 30

When will evolution by natural selection occur?

Answer 30

When a heritable variation leads to differential success in survival and reproduction

Question 31

Allele

Answer 31

Version of a gene

Question 32

Gene

Answer 32

Length of DNA that codes for a protein

Question 33

Natural selection leads to evolution In the form of

Answer 33

allele frequency

Question 34

Allele frequency

Answer 34

Total number of an allele in a gene pool /total number of all alleles in a gene pool

Question 35

Evolution by natural selection

Answer 35

Change in allele frequency in a population over time

Question 36

Total number I alleles in a pop

Answer 36

of individuals X # of alleles

Question 37

Evolution is not always brought on

Answer 37

By natural selection

Question 38

Heritable trait variation ->certain traits naturally selected for ->differential survival->

Answer 38

Differential reproduction-> evolution

Question 39

One kind of allele variation

Answer 39

Allele frequency

Question 40

What are the questions you ask to see if natural selection has occurred

Answer 40

Variation in trait?trait is heritable?was there competition for survival?variation in reproduction?was certain trait naturally selected for?did natural selection occur?

Question 41

What was lamarcks view?

Answer 41

Individuals change in response to environment (false)

Question 42

What was Darwin's views?
