What is the process called when allele frequencies in a population of a species change over time?
Evolution; the change in allele frequencies over time in a population of organisms.
What do biologist call the process when allele frenquencies in a population of a species change over time due to chance?
C:Genetic drift
What do biologists call the process when allele frequencies in a population of a species change over time due to chance?
genetic drift
Which unit of organism evolves and individual a population or a species?
Evolution occurs at the population level, not at the level of an individual organism or a species. Changes in gene frequencies within a population over time drive the process of evolution.
A genetic change which can effect a species fitness?
evolution within a species. the allele frequencies in a gene pool of a population
What term refers to a biologist who narrowly defines species based primarily on minor differences?
A biologist who narrowly defines species based primarily on minor differences is often referred to as a "splitter." Splitting involves dividing a population into multiple species based on minor variations in characteristics.
Biologist have classified how many species?
Over one million species have been classified by Biologist.
Which type of scientist would observe the spread of species of red fire ants?
A biologist
How can nonrandom mating change allel frequencies?
Non-random mating means that individuals of many species have a choice about which partners to mate with. In population genetics, allele frequencies are used to depict the amount of genetic diversity in a species. There is no current research to show nonrandom mating impacts a species genetic diversity.
How do you use a sentence with biologist?
This is my biologist cousin, Jane. Rachel Carson was an American marine biologist and conservationist.
How are a population and community different?
A population biologist studies the number(s) of species as they increase or decline in relation to their density or some environmental factor. Community ecologists study the numbers and interactions of all the species in a given location.
What is it called when no evolution takes place?
A species that does evolve is an open ended species. One that doesn't is the opposite of that.
