BIOD 210 Genetics Final Exam
Complete Questions and Answers
1. who proposed epigenesis
ANS William Harvey
2. A concept that is now known to have correctly hypothesized that a
fertilized human egg undergoes specific developmental events that
eventually lead to the formation of a human.
ANS Epigenesis
3. A concept that a fertilized egg contained a tiny version of a
completely developed adults.
ANS Preformation
1/5
,4. In preformation, the tiny fully sized adult within the fertilized egg is
termed-
ANS homunculus
5. Who proposed the cell theory?
ANS Matthias Schleiden and Theodor Schwann
6. Proposed that all living organisms were composed of organized
structures called cells and that these cells were derived from identical
precursor cells.-
ANS cell theory
7. the concept that livings things could spontaneously generate from
nonliv- ing components
ANS spontaneous generation
8. Who proposed natural selection? What does it entail?
2/5
, ANS Charles Darwn; The origin of species; natural selection believed
that more offsprings were produced than an environment could actually
support. Suvival in a crowded environment would allow only the
strongest to survive.
9. What is an example of natural selection?
ANS For instance, in a mountain envi- ronment, animals that were well-
adapted for climbing steep cliffs or surviving harsh winters would
survive much longer than those that had difficulty balancing on rough
surfaces or that possessed a thin outer covering.
10.Who proposed published work on pea plants?
ANS Gregor Mendel
11.Is natural selection still prominent in todays society?
ANS Yes, We still acquire random mutations that sometimes become
"normal". An example of that is the gene that allows us to digest
lactose. When mammals (humans included) cease breastfeeding, it is
3/5
