MECHANISMS OF EVOLUTION
What are the mechanisms of evolution (5)
natural selection, gene low, gene drift, gene drift, non random mating
Name the types of evolutionary evidence
1. Fossil evidence
2. Comparative anatomy
3. Molecular biology
4. Embryology
What is speciaaation
The process of a new species being made
What is hardy-weinberg equilibrium?
Hardy-Weinberg equilibrium is a principle that states a population's allele and genotype frequencies will remain constant from generation to generation if no evolutionary forces are acting on it
What is the chemical symbol for water?
H2O
Preerences influence partner selection
Non-random mating
What is the law of superposition
the oldest layers are at the bottom and the youngest layers are at the top
What are the two reproductive barriers to speciation
Prezygotic
Postzygotic
What are the five conditions required for a population to be in Hardy-Weinberg equilibrium?
How many cards are in a standard deck of playing cards
52
the movement of genes into and out of a population. It can happen through the migration of individuals or the movement of gametes, and it helps to increase genetic variation within a population.
GEne Flow
What are the three structures for comparative anatomy
1. Homologous
2. vestigial
3. Analogous
The three types of prezygotic barriers
Behavioral isolation
Temporal isolation
Mechanical isolation
: What is no mutation?
One of the five conditions required for a population to be in Hardy-Weinberg equilibrium; it prevents new alleles from being introduced.
What is the hardest natural substance on Earth?
Diamond
the change in the frequency of an existing gene in a population due to random chance, and it has a more significant impact on small
GEnetic Drift
In molecular biology, closely related species have....... genetic sequences
Similar
The two post zygotic barriers
1. Hybrid sterility
2. Hybrid inviability
What is a large (or infinitely large) population size?
The condition that a population must be this size to avoid random fluctuations in allele frequencies.
What is the largest planet in our solar system?
Jupiter
What mechanism of evolution means that individuals with advantageous triats are more likely to survive and reproduce
Natural selection
What is the difference between homologous and analogous structures?
Homologous structures have similar structures but in different species
Analogous structures have similar functions but different internal structures.
What does the process of new species being made stop
1. Inbreeding
or
2.Gene Flow
In the Hardy-Weinberg equations, this variable represents the frequency of the dominant allele.
What is p?
Who was the 20th president in the U.S
James A. Garfield
