A trait that is expressed in an individual as long as at least 1 allele is present is known as a _____________ allele
dominant
DNA has 2 strands, while RNA has
1 strand
All members of all living species in a given area
community
a struggle for limited resources (EX: food or territory)
competition
A mechanism of evolution in which beneficial traits become more common in a population over time
natural selection
an individual with two of the same allele for a given trait is _________________ for that trait
homozygous
This enzyme helps assemble DNA from its building blocks during replication
DNA polymerase
The maximum population that an ecosystem can sustainably support
carrying capacity
A type of relationship in 2 species living closely together interact and at least one organism benefits from the interaction
symbiosis
A type of selection in which a more moderate for of a trait (EG: a medium tail, rather than long or short) becomes more common in a population over time
stabilizing selection
A pattern of inheritance in which neither trait is fully dominant over the other (ex: pink flower from the crossbreeding of a red and white flower) is called
incomplete dominance
During this process, proteins are made based on the instructions from RNA
translation
a limiting factor such as disease, which will operate more strongly when individuals in a population are packed more closely together
density dependent limiting factors
A type of competitive behavior in which organisms compete for mates
courtship behavior
The type of isolation that results from different breeding seasons
temporal isolation
a section of DNA that codes for a trait
gene
The D in DNA and R in RNA stand for the type of sugar in the molecule, __________ and ___________, respectively
Deoxyribose and ribose
A nonliving element in an ecosystem, such as water or climate
abiotic factor
the name of the relationship between a plant-eater and a plant
herbivory
One piece of evidence for evolution is this, in which organisms of different, not closely related species have structures that perform a similar function, despite having different physical structures (EX: bird wings and butterfly wings)
analogous structures
In the ABO blood typing system, these 3 patterns of inheritance govern which blood type a person has
the monomer that makes up DNA and RNA
nucleotide
an area that has a wider variety of species would be said to be more _________ than an area that has fewer different species
biodiverse
The name of a relationship in which one organism benefits and the other is neither benefitted nor harmed.
commensalism
P in the Hardy-Weinberg equilibrium equation P+Q=1
The frequency of the dominant allele
