BIO 182 EXAM 1 QUESTIONS &
ANSWERS (GRADED A+)
changes in allele frequency (control heritable traits) in a population over time -
ANSWERmicroevolution
accumulation of changes that lead to the formation of a new species - ANSWER
changes in populations from one generation to the next (over time and happens in 1
or more heritable characteristics) and results in differential survive and reproduction
(fitness)-some individuals have higher fitness than others - ANSWERevolution
similar characteristics due to a common ancestry - ANSWERhomologies
3 types of homologies - ANSWERanatomical, developmental, molecular
homologous structure, vestigial structures - features that have no current function but
resemble structure in ancestors - ANSWERanatomical homologies
similarities during embryonic development (not observed/present at birth)
humans - gill ridges, bony tail - ANSWERdevelopmental homologies (embryos)
similarities in:
-use DNA as hereditary molecule
-universal genetic code
-in eukaryotes processes (cellular respiration)
-sequences of genes (DNA) and protein - ANSWERmolecular homologies
all members of a species that live in one area at the same time -
ANSWERpopulation
group of related individuals that share a distinctive form (and are capable of
interbreeding- only applies to sexually reproducing species) - ANSWERspecies
similarities between species of non closely related species (different lineages) due to
similar environments - ANSWERconvergent traits
(common characteristics = analogous structures/traits)
led by humans (breeders) - choose a desired characteristic and only individuals with
this characteristic are allowed to breed - ANSWERselective breeding (artificial
selection)
study of genes and genotypes in a population/can measure whether there is change
in a population - is population evolving? - ANSWERpopulation genetics
