Evolution

Question 2

Genotype

Answer 2

Hereditary material - genetic I strict ions for the development of an organism

Question 3

Does genotype fully or partly determine an organism’s characteristics

Answer 3

Only partly

Question 4

Phenotype

Answer 4

Physical expression of the genotype

Question 5

Two parts an organism is partitioned into

Answer 5

Genotype and phenotype

Question 6

What three things must the phenotype provide?

Answer 6

Growth and reproduction (G)Protection (P)Fecundity (F)

Question 7

When an organism concentrates more on one trait (F,P,G) its called a

Answer 7

tradeoff

Question 8

Gene pool is

Answer 8

an abstract assemblage of all genes in a population

Question 9

To find the gene frequency for a certain gene

Answer 9

divide the # of the specific gene bye the total # of organisms

Question 10

How would you find the gene frequency the second generation?

Answer 10

Total # of gene in second gen by total produced in 2nd gen

Question 11

The measure of biological “success” of a genotype is

Answer 11

Fitness (Darwinian/abbreviated)

Question 12

What is fitness?

Answer 12

the number of genome copies an organism places into the next generation

Question 13

To find fitness…

Answer 13

divide the number of reproduced genes by the # of starting

Question 14

What determines if a phenotype will predominate in a population?

Answer 14

The higher the fitness frequency

Question 15

Is fitness an intrinsic characteristic of an organism? (explain)

Answer 15

No, it is a measure of the match between the characteristics of an organism and the conditions/demands of the environment

Question 16

Does one attribute of an organism/phenotype determine fitness?

Answer 16

No, it is the combination of everything relative to the demands of the government

Question 17

What is the function of the phenotype?

Answer 17

To transport as many gene copies as possible from one generation to the next (gene transport machine)

Question 18

Why can we conclude that organisms are designed to be good gene transport machines? (*important*)

Answer 18

The organisms genotypes code for phenotypes that transport more gene copies to the next generation, eventually dominating in a population

Question 19

From a genetic sense, the process of natural selection is…

Answer 19

changes in the realtive frequencies of different genes due to survival and fecundity diffferences

Question 20

“throw away survival machines”

Answer 20

When genes jump through time within organisms

Question 21

Organism-based view

Answer 21

genes are blueprints for converting an egg to organism

Question 22

Gene-based view

Answer 22

organisms are short-lived vessels made by long-lived genes to go through time and space

Question 23

Some genes are _____ that don’t code for phenotypes

Answer 23

parasitic transposable elements

Question 24

Which is easier to understand evolution with?Gene based or organism based view?

Answer 24

Gene based view

Question 25

Do phenotypes evolve because they are good for the species?

Answer 25
