Combined genetic information of all members of a particular population
What is a gene pool?
100
The success of an organism in surviving and reproducing is a measure of this
What is fitness?
100
Scientist who formulated theory of evolution
Who is Charles Darwin?
100
Tourists taking middle spine numbers cacti, not small or large.
What is stabilizing selection?
100
Reach food
What is longer neck?
200
Concept that each living species has descended, with changes, from other species over time.
What is descent with modification?
200
Random change in a small population's alleles frequency
What is genetic drift?
200
mutations and genetic shuffling of alleles resulsts
What is genetic variation?
200
"Naked bunnies" disappearing due to cold.
What is directional?
200
Moths fitness changes in England
What is camouflage? What is becoming darker?
300
Structures that have different mature forms but develop from the same embryonic tissue
What are homologous structures?
300
A change in allele frequency that results from the migration of a small subgroup of a population
What is the founder effect?
300
Given a Population of lizards, the smallest and largest lizards are more easily preyed upon than middle-sized lizards. This kind of natural selection is most likely to occur.
What is stabilizing selection?
300
Cows who prefer red and white flowers, but not pink.
What is disruptive selection?
300
Changes in finches due to food available?
What is beak size?
400
Results in the fitness traits
What is adaptation?
400
The type of selection in which individuals of average size have greater fitness than small or large individuals.
What stabilizing selection?
400
Frequency of Alleles in population remain unchanged
What is genetic equilibrium?
400
Type of selection in which beaks of birds evolve due to the Loss of small seeds in a bird's habitat over time and habitat still has medium and larger size seeds available for birds.
What directional selection?
400
Insects not dying when exposed to DDT (insecticide used in 1940) and must have this fitness.
What is resistance to DDT?
500
Organs of some animals are so reduced in size that they are just vestiges, or traces, of homologous organs in other species
What are vestigial organs?
500
Traits that are controlled by more than one gene, such as human height.
What is a polygenic trait?
500
Two species reproduce at different times
What is temporal isolation?
500
Adaptations of tortoises on Galapagos Islands
What are shell shape and neck length?
500
Adaptation of giraffes to help them reach their food supply.
