unit 1.1

Question 1

Evolution

Answer 1

change (in genome) in a population overtime

Question 2

Population

Answer 2

a group of biological organisms that are similar enough that we can put them together……species= population, species has multiple populations at times

Question 3

What are the two fundamental categories of change in any population?

Answer 3

• transformational process

- variational process

Question 4

What are the three basic types of change that effect change in a biological population?

Answer 4

Natural Selection
Genetic Drift
Mutation

Question 5

natural selection

Answer 5

Natural Selection-has no impact on change, but filters them out, diff. variations. Some flavored over another-no change in DNA

Question 6

genetic drift

Answer 6

Genetic Drift-selecting out individuals due to random chance. no change in DNA

Question 7

mutation

Answer 7

Mutation-change DNA

Question 8

These three basic types of change in biological populations fall into what fundamental category of change?

Answer 8

Natural Selection- variational processes
Genetic drift- variational processes
Mutation- transformational process

Question 9

gene

Answer 9

unit of DNA that has a specific function

-we all have the sam genes but diff alleles

Question 10

genotype

Answer 10

accumulation of all alleles

Question 11

allele

Answer 11

version of a gene

a blood type, b blood type

Question 12

phenotype

Answer 12

physical characteristics of an organisms based on genotype and sometimes environment
