Systematics

3
Vicariance
________ is the physical splitting of a habitat.

4
Biogeography
________ is the study of how species and populations are distributed geographically.
New cards
5
Speciation
________ by polyploidization is driven by chromosome- level mutations and occurs in sympatry.
New cards
6
Dispersal
________ is the movement of individuals from one place to another.
New cards
7
Allopolyploid
________ " (different many- form) "individuals are created when parents of different species mate and then an error in mitosis occurs, resulting in viable, non sterile offspring with two full sets of chromosome.
New cards
8
Autopolyploid
________ " (same- many- form) "individuals are produced when a mutation results in a doubling of chromosome number and the chromosomes all come from the same species.
New cards
9
Taxonomy
________ is the practice of describing, naming, and classifying individual species.
New cards
10
hybrid zone
A(n) ________ is a geographic area where interbreeding occurs and hybrid offspring are common.
New cards
11
ancestral population
A monophyletic group, also called a clade or lineage, consists of a(n) ________, all of its descendants, and only those descendants.
New cards
12
group of populations
A species is defined as an evolutionarily independent population or ________.
New cards
13
Biological species concept
the main criterion for identifying species is reproductive isolation.
New cards
14
Prezygotic isolation
which prevents individuals of different species from mating successfully
New cards
15
Postzygotic isolation
in which the hybrid offspring of matings between members of different species either do not survive or do not reproduce.
New cards
16
morphospecies (“form-species”) concept
researchers identify evolutionarily independent lineages by differences in size, shape, or other morphological features.
