TERM 10

Cells lining stomach are replaced how often

DEFINITION 10

Every Three days

Natural Selection

Only evolution force that allow adaptation

TERM 17

Genetic Drift

DEFINITION 17

Changes in gene frequency due to random events; especially

in small populations ex. Bottle neck and founder effect

TERM 18

Bottleneck

DEFINITION 18

population undergoes severe decreases in size later

populations recovers and grows But retains limited genetic

variation

TERM 19

Founder effect

DEFINITION 19

Allele frequency of a small population that becomes isolated

is different from original population

TERM 20

Fisher's Runaway Selection

DEFINITION 20

Theory where attractive traits are selected Theory where non

adaptive traits are selected for.

Directional

This type of selection shifts frequency in one direction

TERM 22

Allele

DEFINITION 22

particular version of a gene

TERM 23

Heterozygous

DEFINITION 23

When an organism has 2 alleles at a single locus

TERM 24

Dominant

DEFINITION 24

A gene that masks the expression of another gene

TERM 25

Gene Interaction

DEFINITION 25

When two or more genes determine

Gene Imprinting

When allele expressed is determined by which parent

donates

TERM 32

Growth promoting

DEFINITION 32

Paternally imprinted genes tend to be

TERM 33

Mutagen

DEFINITION 33

Chemical that increases the rate of mutation

TERM 34

Ionizing Radiation

DEFINITION 34

Mutagen that creates free radicals

TERM 35

Transposition

DEFINITION 35

Mutation where locus of gene is altered

Xeroderma Pigentosum

Disorder where UV damage cannot be repaired

TERM 37

Cell replication

DEFINITION 37

Most oncogens are associated with this process

TERM 38

Allopatric Speciation

DEFINITION 38

Speciations within different geograohic locations

TERM 39

Allen's Rule

DEFINITION 39

Extremities are shorter as you go North

TERM 40

Genetic Drift is ____proportional To population

size

DEFINITION 40

Inversely

Cohort

Population of individuals in an age range

TERM 47

Cost of Reproduction

DEFINITION 47

Reduction in future reproductive potential from present

efforts

TERM 48

Competitive Exclusive

Principle

DEFINITION 48

Idea where no tow species can occupy same niche

indefinitely

TERM 49

Iteroparity

DEFINITION 49

Species with high parental investment, higher offspring

survival many species produce fewer offspring/ year but

reproduce for more years

TERM 50

Lifetime

DEFINITION 50

Natural Selection favors a life-history that maximizes

___reproducive history

Incomplete dominance

offspring differ from both parents e.x. Snapdragons when

homozygous reds cross with homozyous white--> all pink F

TERM 52
