QUESTIONS AND VERIFIED
CORRECT ANSWERS
GRADED A+ LATEST 100%
GUARANTEED PASS
Bacteria, Achaea , Eukarya - CORRECT ANSWER-the three domains
Hybridization - CORRECT ANSWER-merging of two species into one; merging lines on phylogenic
tree
Lateral gene transfer - CORRECT ANSWER-in bacteria, useful information is being transferred,
fused
Sexual reproduction - CORRECT ANSWER-fusion of genomes
Evidence for evolution - CORRECT ANSWER-changes through time, extinction, vestigial traits,
inter-relatedness
Evidence for natural selection - CORRECT ANSWER-industrial melanism, antibiotic resistance,
beak size in Galapagos finches
,Darwin and Wallace - CORRECT ANSWER-proposed the theory of evolution
Ring species - CORRECT ANSWER-Five populations and the one on the left can populate with
the one right beside it, that one can populate with the one right beside it, but the two species
on the end of the linear relationship overlap but cannot reproduce with each other, only their
adjacent populations
Speciation by polyploidization - CORRECT ANSWER-method of new species emerging by
genome duplication
Transitional forms - CORRECT ANSWER-fossils with traits that are intermediate between earlier
and later species
Homologous traits - CORRECT ANSWER-a similarity that exists in species that was inherited from
an ancestor
Genetic homology - CORRECT ANSWER-similarity among species in DNA sequences, gene
content, or other genetic attributes
Developmental homology - CORRECT ANSWER-similarity among species in embryonic traits
Structural homology - CORRECT ANSWER-example of an organ or bone that appears in different
animals, underlining anatomical commonalities demonstrating descent from a common
ancestor
Vestigial traits - CORRECT ANSWER-often homologous to structures that are functioning
normally in other species
Variation - CORRECT ANSWER-mitochondrial DNA substitution of single codons
, Heritability - CORRECT ANSWER-traits get passed down from generation to generation
Candidate gene approach - CORRECT ANSWER-applying info from closely related species that
are more known
Fitness trade-off - CORRECT ANSWER-compromise between traits, in terms of how those traits
are adapted for the environment
Genetic correlation - CORRECT ANSWER-when selection favouring alleles for one trait causes a
correlated but suboptimal change in allele for another trait; changing one feature (or gene)
often affects multiple features
Historical constraints - CORRECT ANSWER-Present variation biases future possibilities
Formal constraints - CORRECT ANSWER-Evolution needs to work within the laws of physics
Temporal constraints - CORRECT ANSWER-Evolution occurs by mutation and it takes time for a
series of useful mutations to occur
Hardy-Weinsberg equation (p^2 + 2pq + q^2 = 1 ) - CORRECT ANSWER-estimated expected
genotype frequencies from allele frequencies
Hardy-Weinsberg principle - CORRECT ANSWER-a null hypothesis that predicts what genotype
frequencies should be given known allele frequencies
Genetic drift - CORRECT ANSWER-causes allele frequencies to change by chance
