Four Forces
The only force that adds new genetic material.
What is mutation?
The original allele for human blood type
What is type O?
Lamarckian Inheritance is the belief that...
What is: organisms evolve within their lifetime to better survive, ex: giraffe's neck will stretch to reach leaves rather than being born with the trait.
The made up organism is Fettuccini Alfredo. From this name, identify the genus and species.
What is: genus is Fettuccini, species is Alfredo?
Define an allele.
Gne flow is positively coordinated with _______ ________.
What is genetic diversity?
Race is not real biologically but is real _____ and _______.
What is socially and culturally?
The Scottish Geologist who proposed landscapes change, form, and erode over time for millions of years at a uniform rate.
Who is James Hutton?
How old is the current mutation for light skin in humans?
What is approximately 10,000 years ago?
The two major steps of protein synthesis are:
What is transcription and translation?
Genetic drift comes in three forms:
What is:
1. Wrong place, wrong time
2. Founder effect
3. Genetic bottleneck
Fuentes' definition of race
What is a population that has unique genetic markers that differentiate it from all other populations within the species caused by evolutionary forces?
A scientist who believed a population can only get as large as its food supply allowed.
Who is Thomas Malthus?
Sickle cell anemia is an example of ________ polymorphism.
What is balanced?
One organism has 36 chromosomes while another has 15. The more complex organism is:
Neither, since the number of chromosomes is about packaging rather than complexity.
Natural selection has three forms of positive selection:
What is:
1. Directional
2. Stabilizing
3. Disruptive
The HLA system has around __ to __ genes with ___ to ____ alleles each.
What is: 5-7 genes with 300-500 alleles each?
A scientist who compared the anatomy of fossilized organisms and believed in catatrophism.
Who is Georges Cuvier?
What is mutation and natural selection?
Translate the following nucleotide base from DNA to mRNA to tRNA: A C T.
A C T -> U G A -> A C U
A population of 80% blue and 20% green beetles live in a park isolated by traffic. The park floods one day, killing lots of them. Only green beetles are left due to luck. Now all of the beetle population at that park are green. This is an example of?
Genetic drift, specifically wrong place, wrong time and genetic bottleneck.
What are AIMs and what do they tell us about the human population?
What is AIMs (or Ancestry Informative Markers) help to identify the ancestry of human populations to see if ancestors show specific patterns of genetic variation?
Gregor Mendel was a monk who observed peas and came up with ____________, the idea that traits are inherited independently without blending into an average.
What is Principle of Independent Assortment?
Most of the variation in blood type in human populations comes from this force of evolution:
What is gene flow?
Tell me the difference between pleiotropic and polygenic.
What is: pleiotropic is one gene affecting many traits while polygenic is many genes affecting only one trait?
