Genes and Variation
Genetic Change
Process of Speciation
Natural Selection
Evolution Since Darwin
100
combined genetic information of all members of a particular population
What is gene pool?
100
each time an organism reproduces, it copies of genes to its.
What is offspring
100
A group of organisms that breed with one another and produce fertile offspring.
What is species?
100
What leads to a single gene.
What is natural selection?
100
The first evolutionary biologist.
Who is Charles Darwin?
200
the success of an organism in surviving and reproducing is a measure of this.
What is fitness?
200
the three ways natural selection can affect the distributions of phenotypes
What is directional selection , stabilizing selection, disruptive selection ?
200
the type of isolating mechanism that occurs when two populations are capable of interbreeding but have differences in courtships rituals or other reproductive strategies that involve behavior.
What is behavioral isolation ?
200
free pass
What is get the points?
200
As Darwin developed his theory, he didn't know about what?
What is heredity?
300
traits that are controlled by more than one gene, such as height, are known as this
What are polygenic traits?
300
when traits are controlled by more than one gene, the effects of natural selection are.
What is more complex?
300
the gene pools of two populations must become seperated for them to become.
What is speciation?
300
Natural selection can affect the distributions of this.
What are phenotypes?
300
Darwin has no idea how ___________ pass from one generation to the next.
What are heritable traits?
400
in sexual reproduction, these can recombine to produce different genotypes, resulting in different phenotypes and variation within a population.
What are alleles?
400
a situation in which allele frequencies change as a result of the migration of a small subgroup of a population
What is the founder effect ?
400
Natural selection on a single-gene trait leads to this.
What are the changes in allele frequencies leading to evolution?
400
The first to study how mutations form was Darwin, true or false.
What is false?
500
the random change in allele frequencies in a population. It happens when a small group of organisms colonizes a new habitat.
What is genetic drift?
500
the five conditions that are required to maintain genetic equilibrium from generation to generation.
What is there must be random mating, the population must be very large, there can be no movement into or out of the population, no mutations, and no natural selection?
500
The process by which individuals are better suited to their environment in natural selection are those who reproduce most successfully.
What is survival of the fittest?
500
Mutations, gene shuttling, and relative frequencies are examples what this person overlooked.
