ASU BIO 182 EXAM 2 LATEST ACTUAL
QUESTIONS WITH VERIFIED
ANSWERS
◉ hybridization.
Answer: sometimes 2 individuals looks similar without being from
the same species
◉ Hybrid.
Answer: an animal carrying genes from two different species.
Usually infertile, even if it frowns into adulthood
◉ biological species.
Answer: -two organisms are the same species if both individuals
alleles end up in the same individual in future generations
‑two organism belong to same species of their alleles can end up in
the same organism
◉ Pre-zygotic.
Answer: -isolates species
‑different habitats
‑active at different times
, ‑aren't sexually attractive/genitals don't match/gametes can't fuse
◉ Post-zygotic.
Answer: -isolates species
‑hybrids die young/are sterile
‑very strong selection against attraction to other species
◉ Allopatry Speciation.
Answer: -populations occur in different places
‑geographically isolated
‑produces different species
‑diverges down 2 evolutionary pathways and can no longer
interbreed
◉ sympatry speciation.
Answer: -occurs in populations in The same geographical area
‑mutations
‑cannot produce fertile and viable hybrids (post zygotes isolating
mechanism)
◉ Abiotic factors.
Answer: -Temperature
