15 Cards in this Set

  • Front
  • Back
changes in population genotype and allele frequencies for the next generation
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
Study and reconstruction of phylogenies
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

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
-complex multicellular organisms w/ tissues and organs
-plant cells have walls containing cellulose
- most but not all do photsynthesis
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
