Synthetic Theory
What is the process in which pieces of DNA are proken to produce new combinations of alleles?
Recombination
The chances of suriviving are big or small if the gene pool is small
Less posibilities
What does a change in allele frequency over time indicate?
Evolution
who were the contributors of the synthetic theory?
Dobzhansky, Mayr, Simpson, Ronald Fisher, J. B. S and Sewall Wright.
Polar Bear evolved from:
Grizzly Bear
What causes mutations?
Changes in the DNA sequence of an organism, germline or somatic
What happen if the gene pool is large?
the population has more chances of survive enviromental challenges.
Formula of Allele Frequency
f(A)=(number of A alleles)/(Total alleles)
In which other way is Ronald Fisher know?
father of the modern statics.
In which other ways synthetic theory is known?
Modern Synthesis or Neodarwinism
A variation in the frequence of different characteristics in a small popoulation
What happen if the population reproduce between siblings or cousins?
it has less ability to survive enrivomental challenges
How can mutation can affect allele frequency in a population?
Increasing genetic variation
How Mayr helped to define the synthetic theory?
By proposing the “Biological Species Concept”
What is Speciation?
Is when new species are formed from an initial specie
Gene flow stands for:
Movement of certain individuals from one population to another/migration
Complete the sentence: A large gene pool has more...
diversity of alleles.
What does it mean if an allele becomes "fixed" in a population?
When its frequency reaches 1 (100%)
What was the fun fact about Ronald Fisher and J. B. S.
That they die at the same age
What does population genetics states?
It states that it is not individuals who evolve, but population
Recombination occurs in:
Meiosis
What means gene pool?
total collection of genes in the same population.
How is allele frequency used in studying human diseases?
Identify how common a disease-related gene variant is in a population
Who died at the age of a 100 years?
Ernst Mayr
What was the thing that crockroaches with the rare gene dislike?
They dislike glucose
