|
Microevolution
|
changes in population genotype and allele frequencies for the next generation
|
|
|
Macroevolution
|
isolation mechanisms include physical seperation, selective mating, and sterile offspring
|
|
|
Biological Species Concept
|
Populations that are capable of reproduction, but cannot reproduce w/ other species
|
|
|
Evolutionary Species Concept
|
a single descent (lineage) that stays distinct from other lineages. About 10 million
|
|
|
Systematics
|
Study and reconstruction of phylogenies
|
|
|
Cladogram
|
branching diagram based on cladistic analysis that represents a phylogeny Includes outgroup and ingroup
|
|
|
Two prokaryotic Domians? Their kindgdoms?
|
Domain Archea- Kingdom Archaebacteria
Domain Bacteria- Kingdom Eubacteria |
|
|
One Eukaryotic domain? It's four kindgoms
|
Eukarya.
FAPP Fungi, Animalia, Protista, Plantae |
|
|
Protista. Ex?
|
-single/simple multicellular organisms
-protozoa, algae, watermolds, and slime molds -dumpground for what is prokarytic but doesn't fit w/ eukaryotic kindom |
|
|
Fungi. Ex?
|
-organisms w/ cell walls containing chitin
- most are multicellular - molds and yeasts |
|
|
Platae.
|
-complex multicellular organisms w/ tissues and organs
-plant cells have walls containing cellulose - most but not all do photsynthesis |
|
|
Animalia.
|
multicellular, eat others for nourishment, no cell walls, organs, and usually motile
|
|
|
Zygotic Meiosis
|
protists, zygote immed goes through meiosis, diploid zygote never undergoes mitosis, mitosis only in haploid cells, making haploid individuals
|
|
|
Gametic Meiosis
|
Animals. meiosis produces gametes that never undergo mitosis, zygotic undergoes mitosis, making diploid individuals
|
|
|
Alteration of Generation w/ Sporic meiosis
|
plants/ algae
zygote undergoes mitosis, making diploid individuals § some diploid cells undergo meiosis to make haploid spores (sporic meiosis) § mitosis in haploid spores, making haploid individuals § some spores develop into gametes, which undergo syngamy to make a diploid zygote § thus, two bodies in one life cycle – two instances of mitosis in one life cycle |
