Equador

What is a population?
A group of organisms of the same species living together in the same geographic region
100
What is the biological species concept?
a group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring.
100
Anatomical structures that are fully developed in one group of organisms but are reduced and have no function in similar groups
Vestigial

A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb. The frequency of the BB genotype is .35. What is the frequency of heterozygous rabbits?
the frequency of the heterozygous rabbits is 0.484

What are structures that originated from a common ancestor but are currently used for a variety of purposes. Same structure different function
Homologous structures
200
What is a sudden change in the environment, such as a fire or flood, that may drastically reduce the size of the population?
Bottleneck effect
200
What is the existence of biological factors (barriers) that impede members of two species from producing viable, fertile offspring
Reproductive isolation

***DAILY DOUBLE***
a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships in the phylogenetic tree?
outgroup, basal taxon

A hypothetical population of 10,000 humans has 6840 individuals with the blood type AA, 2860 individuals with blood type AB and 300 individuals with the blood type BB. What is the frequency of each genotype in this population?
What is AA = 0.684 / AB = 0.286 / BB = 0.03

According to Darwin what are 3 factors that contribute to Natural Selection
overproduction, variations, competition, survival of the fittest, inheritance
300
What are TWO sources of variations in a population?
sexual recombination, mutations
300
What are barriers that prevent members of different species from reproducing by hindering fertilization?
Prezygotic barriers
300
The two major types of evidence that are used to analyze species' evolutionary relationships and develop phylogenetic trees.
What are molecular (DNA, Amino Acids) or Morphological data

A population of birds contains 16 animals with red tail feathers and 34 animals with blue tail feathers. Blue tail feathers are the dominant trait. What is the frequency of the red allele?
0.566
400
Inherited characteristic that increases an organism's chance of survival
adaptations
400
What is a mode of selection that favors variants at both ends of the distribution
Disruptive selection
400
What is the term used to describe periods of apparent stasis punctuated by sudden changes observed in the fossil record.
Punctuated equilibrium
400
What is the process of rapid speciation in the presence of unfilled niches.
adaptive radiation
400
The ability to taste PTC is due to a single dominate allele "T". You sampled 215 individuals in a biology class, and determined that 150 could detect the bitter taste of PTC and 65 could not. What is the predicted frequency of the recessive allele (t)?
0.55

What is the evolution of individual species with similar features but from different lineages. (torpedo shape of penguin, dolphin, tuna)
convergent evolution

A recessive allele that causes polydactylism is found in a usually large percentage of the Amish of Lancaster County, PA. This is an example of....
The founder effect

What is the speciation that occurs in populations that live in the same geographic area?
Sympatric speciation

The trait for 'male-pattern baldness' is a recessive trait encoded for by "b". Non-balding is encoded for by a dominant allele encoded for by the letter "B". A street survey conducted by Hair Club for Men found that out of 1000 men, 640 have a full head of hair. What is the frequency of the homozygous dominant genotype?
BB = 0.16
