Gene Expression and Regulation
This is a chromosomal mutation where two or more genes are swapping places within the same chromosome
What is an inversion
This is what happens when there is a huge decline in the numbers of a population due to an event and the gene pool is drastically limited moving forward
What is the Bottleneck effect
these are the three types of dispersion that can be seen in organism populations
What are random, uniform, or clumped
In Mendelian Genetics there is a term for homozygous organisms that if allowed to self pollinate, will only produce the same type. They are known as this
What are Truebreeding
This is the amount of energy that is able to be transferred from one trophic level to another
These scientists were able to prove that DNA is the genetic material by using radioactive Phosphorous and Sulfur as markers
Who are Hershey and Chase
This is when there are species with no common ancestor that eventually are resembling one another due to similar selective pressures
What is Convergent Evolution
This is the limit of a population based on resources and other factors
What is the Carrying capacity
Gregor Mendel set out to explain how hereditable information is transmitted. He gave these three laws that explain the process
What are Law of Dominance, Independent assortment, and Segregation
These are the distances between genes on a chromosome and can be calculated as a percent of recombination to figure out how far genes are from one another
What are Map units
In DNA replication this enzyme is responsible for relieving stress and pressure at the top end of the strand so that it does not break
What is Topoisomerase
These are the three modes of selection and can lead to drastically different looking populations in a historical timeline
What are Disruptive, directional, and stabilizing
This is the type of growth strategy that is seen in humans and most mammals that brood their young and do not have many offspring
What is the K-Strategy
In a cross between two plants that are heterozygous, this would be the probability of an offspring with the genotype YyRR.
What is 2/16 or 1/8
This is the term form when in non-mendelian genetics there is a chance that a gene at one locus will impact the expression of a gene at another locus.
What is Epistasis
This enzyme is highly important in ensuring that proper base pairs are added as compliments to the template strand to build the new strand in DNA replication
What is DNA Polymerase 3
This process of changing allele frequencies within a population is known as this type of evolution
What is Microevolution
The specific biotic and abiotic resources that an organism or species will use within its environment are known as this
What is the Organisms Niche
When two traits are specifically dominant we get the chance of both showing at the same time, known as this, or we can have a blending of the two traits known as this. (2 responses in order)
What are codominance and Incomplete dominance
In an ecosystem there can be a build up of toxins within the fat cells of organisms. As they are eaten and energy transferred in the trophic system, this process can happen and cause issues
What is Biomagnification
This is a type of repair needed in DNA when several nucleotides are matched wrong and then there is this type of repair when a large segment needs to be cut out and replaced. (2 responses needed)
What are Mismatch repair and Excision Repair
Sympatric speciation can occur if there is this type of barrier that does not allow for the formation of an offspring but allows the attempt of mating.
What is a prezygotic Barrier
What are Parasitism, commensalism, and mutualism
In non-mendelian genetics we know that certain genes can impact multiple traits. This is known as which type of inheritance
What is Pleiotropic inheritance or Pleiotropy
These organisms are not vast in numbers but still have a huge impact on ecological systems and communities and are required for the delicate balance.
What are Keystone Species
