BIOL 3410 Exam 2 Better Questions With Complete
Solutions
Intrasexual
Male-Male competition. evolution of male weaponary and
fighting ability.
Operational Sex Ratio
ratio of males to females capable of reproducing at a given time
what leads to male biased operational sex ratio
slower rate of reproduction by females
Life history theory
reproductive success over the course of the organism's entire
lifespan
Fecundity
fertility of female.
Senescence
deterioration of biological function as an organism ages
Antagonistic Pleiotropy
when a mutation is beneficial for reproduction, but detrimental
for surviving at an old age
Mother Hypothesis
, selection against older mother's because they are less capable of
raising their young, and more likely to die during childbirth
Grandmother hypothesis
selection favors elderly women who offers resources and
wisdom to family
Biological Species Concept
interbreeding populations that are reproductively isolated from
other populations
Morphological Species Concept
Species that differ based on structure and/or characteristics
Phylogenetic Species Concept
smallest group possible that share a common ancestor
General Linkage species concept
each species is a metapopulation that sperated from other
metapopulations
Microbial Speciation
Bacteria have "core" genome, but all other genes are different
because of horizontal gene transfer
Pan-Genome
combination of all genes of all populations within the species
what does microbial speciation line up with
general linkage species concept
