1. Genetics, it’s not just Spiderman and X-men!
GLE: Students will be able to understand that organisms pass on information in their life cycle and that an organisms characteristics are determined by both genetic and environmental influences

2. It’s not just this…

3. X men? …….. Or this!

4. Pre-Unit Activity: Genetics
Draw genetics – 5 minutes

5. What is Genetics? Genetics = the science of heredity. Heredity
= characteristics passed on from parent to offspring (we’ll get more specific later in the semester).

6. So what are some traits that can be passed on from parent to offspring?

7. So what are some traits that can be passed on from parent to offspring?
Eye color
Hair color
Talents
Personality

8. Genetics…just a lot of words…break it down
Gene = units of heredity
Contained within each DNA molecule

9. What is Genetics (cont.)
From a textbook:
= “The discipline has a rich history and involves investigations of molecules, cells, organisms, and populations, using many different experimental approaches. Not only does genetic information play a significant role during evolution, its expression influences the functioning of individuals at all levels. Genetics thus unifies the study of biology and has had a profound impact on human affairs.”
HOLY CAMOLY? What does that all mean?
TO READ YOUR TEXTBOOK, GO SLOW AND BREAK IT DOWN

10. History!
Most significant scientific findings were obtained in the 19th century (that’s the 1800’s folks).
But what led up to that….

11. History: Prehistoric Times
Domestication of animals to serve various roles.
What are some examples?

12. History: Prehistoric Times
Cultivation of plants.
Examples?

13. History: Prehistoric Times
So…
Human awareness of heredity was thus apparent during prehistoric times.

14. History: The Greek Influence
Hippocrates and Aristotle
( BCE)
More attention directed to heredity
Relation to humans
Mostly related to sperm and egg

15. 1600 - 1850: The Dawn of Modern Biology
Charles Darwin
Gregor Mendel
William Harvey
Theory of epigenesis = an organism is derived from substance present in the egg, which differentiate into adult structures during embryonic development

16. 1600 - 1850: The Dawn of Modern Biology
Gregor Mendel:
Austrian monk
born 1822
While in monastery was put in charge of the garden
grew peas and other vegetables
observed different traits in peas:
some tall and other short
some smooth and others wrinkled

17. Charles Darwin and Evolution
Born in England
His father (a doctor) saw no future for a naturalist so sent Charles to study medicine.
Joined the Clergy and received his B.A. and joined a survey ship to be the, “conversation companion” to the captain.
H.M.S. Beagle ( )
At the same time of Darwin, Alfred Russel Wallace similar theories.

18. Charles Darwin and Evolution
1859 published the book-length statement of evolutionary theory, “The Origin of Species.”
“The laws governing inheritance are quite unknown; no one can say why the same peculiarity in different individuals of the same species, and in individuals of different species, is sometimes inherited and sometimes not so; why the child often reverts in certain characters to its grandfather or grandmother or other much more remote ancestor”

19. Charles Darwin and Evolution
Geological, geographical, and biological observations convinced him that existing species arose by descent with modifications from other ancestral species.
Theory of Natural Selection

27. Advances in Agriculture and Medicine from Genetics!
Plants (results in more food):
Improved in 4 major ways:
Enhanced potential of more growth
Increased resistance to pests & predators
Increased nutritional amounts
Combination of traits from 2 strains
Ex) Cauliflower/broccoli, rye/wheat, apple/pear
