Portage: Genetics (Module 1)
1. early selective breeding <Ans> choosing to breed certain animals/plants
for their preferred traits to benefit humans
2. William Harvey <Ans> proposed epigenesis and contradicted preformation
3. epigenesis <Ans> concept that hypothesized that a fertilized human egg
undergoes development events that lead to the formation of a human
4. preformation <Ans> fertilized egg contains a tiny developed adult
5. homunculus <Ans> tiny developed human
6. Schleiden and Schwann <Ans> developed the cell theory
7. cell theory <Ans> idea that all living things are composed of cells, cells are
the basic units of structure and function in living things, and new cells are
produced from existing cells
8. spontaneous generation <Ans> living things could spontaneously generate
from non- living components
9. Charles Darwin <Ans> wrote The Origin of Species and theorized natural
selection
10. natural selection <Ans> more offspring were produced than what could be
supported from the environment
1/5
, - leads to struggle for survival so offsprings would only inherit the most desirable
traits for their certain environment to survive
11. Gregor Mendel <Ans> proposed how traits were inherited from each generatio
--only explains variations and not heredity
--basic of trait transmission
12. genetics <Ans> study of heredity, understanding genes and how they pass
traits
13. chromosomal theory of inheritance <Ans> both heredity and development
depend- ed on passing down of genetic info vis the chromosomes
-- equally passed down from each parent
14. todays genetics <Ans> theory of inheritance + mendel's genetic teachings
15. genes <Ans> traits controlled in pairs
--transferred from parent to offspring and held to determine the characteristic of each
offspring
16. gene pairs <Ans> two alleles, split from egg and sperm and goes into offspring
17. chromosomes <Ans> threadlike structures made of DNA molecules that
contain the genes, found in the nucleus of the cell that holds genetic material
-- exists homologously
18. diploid <Ans> containing two complete sets of chromosomes, one from each
