Unit 10 Review (part 2)

reminants or remains of organisms that lived long ago

body parts that are similar in structure but may differ in functionality

Study of developmet from embryo to adult hood

comparing bodily fluids like hemoglobin or blood

comparing where an organism lives or where it's ancestors lived

comparing body structures like jaws, skulls, teeth and bones

humans choosing desirable traits of domesticated organisms to breed

the entire collection of alleles or genes among a population at any one time

small-scale changes in allele frequencies over generations of time

3 things that can cause genetic variation in organisms that reproduce sexually

sexual repro alone will not change the gene pool without other factors operating

p^2 represents

2 pq represents

define an organisms "fitness"

3 main causes of evolutionary change within microevolution

when the genetic make up of a small icolated population is not likely to be the same as the original population

a cause of genetic drift attributable to colonization individuals from a parent population

the type of environmental impact that favors intermediate phenotypes in relatively stable environments

this type of selection shifts the overall make up of the population by acting against individuals at one of the phenotypic extremes. Most common during periods of environmental change or when individuals migrate to new habitats with different conditions

environmental conditions are varied in a way that favors both the extremes in phenotypic expression

Differences between males and females is called
