15
Q

When a population is not evolving, it is in a state called

A

Hardy-Weinberg Equilibrium

16
Q

Refers to the genetic makeup of an organism.
It describes an organism’s complete set of genes.

17
Q

Refers to the observable physical properties of an organism.
It includes the organism’s appearance, development, and behavior.

18
Q

Percentage of Allele in a population

A

Genetic Frequency

19
Q

Give the 4 Mechanisms of Evolution

A

Mutation, Gene Flow, Genetic Drift, Natural Selection

20
Q

(Mechanisms of Evolution) The original source of all genetic variation. It creates a new DNA sequence for a particular gene creating a new allele.

21
Q

(Mechanisms of Evolution) It involves the movement of genes into our out of a population due to either the movement of individual organisms or
their gametes

22
Q

(Mechanisms of Evolution) It involves changes in allele frequency due to chance events literally “sampling error” in selecting alleles for the next generation

A

Genetic Drift

23
Q

(Mechanisms of Evolution) It occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit
It can survive and reproduce in a given environment

A

Natural Selection

24
Type of Genetic Drift in which a population is sharply reduced in size, due to certain events, leading to a loss of genetic diversity.
Bottleneck Effect
25
Type of Genetic Drift in which a small group separates from a larger population, establishing a new population with a gene pool that may differ from the original population.
Founder Effect
26
What term is used to describe new species forming from a common ancestor
Speciation
27
Why is the survival of the fittest important for evolution
It allows the passing on of positive traits
28
Why mutations are important?
They bring the genetic variation needed for a population to evolve
29
Refers to large-scale changes that occur over extended time periods such as the formation of new species and groups
Macroevolution
30
Refers to small-scale changes that affect just one or a few genes and happen in populations over shorter timescales
Microevolution
31
What evidence of evolution explains that the common structures are shared in the embryo stage and disappear by the time the embryo reaches the juvenile or adult form
Evidence from Embryology
32
The structures with the same set of bones with different function
Homologous Structure
33
The structures that perform the same function but have very different embryological development or set of structures like bones
Analogous Structure
34
What evidence of the evolution has the same genetic material (DNA) The same or highly similar genetic codes The same basic process of gene expression (transcription and translation) The same molecular building blocks, such as amino acids
Evidence from Molecular Biology
35
What evidence of evolution explains that similar organisms may also be found in different locations which could mean that the two places were previously connected
Evidence from Biogeography
36
What evidence of evolution explains that the records found in the rocks show a gradual evolutionary descent from simpler to more complex life forms
Evidence from the fossil record
37
The appendix and tailbone are examples of
vestigial structure
38
Why do scientist look for fossils?
to derive evolutionary relationships
