100
A change in genetic material which is th source of genetic variation
What is a mutation?
100
A group o9f organisms that share similar characteristics and can interbreed to produce fertile offspring
What is a species?
100
mutations and gene shuffling
What are main sources of genetic variation?
100
when there no changes in the allele frequencies (the genes in a gene pool) in a species
What is genetic equilibrium?
100
natural selection acts directly on
What is phenotype?
200
A group of organisms tha can interbreed and share common characteristics.
What is population?
200
a trati that is controlled by a single gene that has 2 alleles
What is a single - gene trait?
200
all of the genes available in a population
What is gene pool?
200
ideal large population were there are no migrations, mutations, or random mating.
What is Hardy-Weinberg Principle?
200
the situation in which alolele frequencies in the gene pool remain constant is called
What is genetic equilibrium?
300
Means genetic variablility can only occur through muations.
What is the way genetic mutations occur in asexual reproduction?
300
Darwin's term for what a genetic change has when it is favored by natural selection
What is fitness?
300
random change in the frequency of alleles of a population over time
What is genetic drift?
300
theroy that changes in a species occur over a long period of time
What is gradualism?
300
what situation might exist in a population if some flowers open at midday and others open late in the day
What is temporal isolation?
400
when meiosis occurs to produce gametes
What is sexual reproduction?
400
traits such as coloraton, odors in plants and animals, competitive strenght, and courting behaviors
What are important traits fo successful mating?
400
the movement of populaton from one place to another
What is migration?
400
periods of abrupg changes in a species after long periods of little change--such as sudden changes in species size du to environmental factors
What is punctuated equilibrium?
400
a small group of individuals in a particular population emigrate to another area and establish a new population is described as
What is founder's effect?
500
The study of evolution from a genetic point of view
What is population genetics?
500
the observable physical or biochemical characteristics of an organism, as determined by boht genetic makeup or enviornmental influence
What is phenotype?
500
the movement of genes into or out of a population, which increases th genetic variability of the recieving population
What is gene flow?
500
a number of species split off from a common ancestor/
What is divergent equilibrium?
500
a change in the genetic makeup of a cell is
What is a mutation?
