What is a gene pool and how is it affected by natural selection?
A gene pool is the total number of genes of every individual in an interbreeding population. Which is like having every single gene of a population into one big pool (population).
What is an example of an open population in science?
a population where all 4 factors affect the population or Group of individuals organisms that belong to the same species that live in the same area
What is combined sciences?
Combined Sciences means that all the man sciences are combined together in the subject. That means Physics,Chemistry,Biology together.
Where will you find variation within a species?
variation within species can be found in all the species. The differences we see between individuals in a species are affected by five processes, usually acting in combination with one another:1. Mutation- these are changes in the genetic structure occurring through breaks in DNA, errors in copying or changes in sequence. This is the ultimate source of all variation.2. Selection is a force which decreases an individuals ability to reproduce. For example, genetic variation in the ability of a tree species to survive severe drought may cause some individuals to die while others survive and reproduce. An event like this may decrease the overall diversity of genes (alleles) in a population but a change in the overall genetic makeup of the population is produced.3. Migration is the movement of genes into or out of a population. This includes pollen or seeds blowing into the population from a source that is otherwise considered to be a separate population.4. Random drift is a chance event unconnected with the genetics of an individual that affects the ability to reproduce. Random drift can be thought of as "dumb luck." A lightening strike or animal damage that kills a tree which is not directly related to the tree's genetic makeup can be thought of as random drift.5. Nonrandom mating reflects the fact that some individuals in a population are more likely to mate with one another than others in the population. In a forest, a tree's flowers are more likely to be fertilized by nearby individuals.
Which of these conditions should completely prevent the occurence of natural selection in a population over time?
All varation between individuals is due only to environmental factors
What combined alleles of all the individuals in a population called?
We call these genes the genome.
What is a gene pool consists of all the genes within a?
A gene pool consists of all the genetic information carried by the individuals in a population. It includes all the different alleles for each gene present in the population. Changes in the gene pool, such as through genetic drift or natural selection, can lead to evolution within a population.
What statement describes a gene pool?
All of the alleles in one populationAll of the alleles in one population
Immigration of individuals to a population in Hardy-Weinberg equilibrium will NOT upset the equilibrium if?
the immigrants do not introduce new alleles to the population and do not have a significantly different allele frequency from the existing population. Additionally, the immigrants must not change the population size significantly by either increasing or decreasing it.
What is the term for all the type of alleles that exist in the population?
gene pool
What does it mean when an allele reaches fixation in a population?
When an allele reaches fixation in a population, it means that all individuals in the population carry that specific allele, and no other alleles for that gene are present. This can happen through natural selection, genetic drift, or other evolutionary processes.
What is the total of all the alleles of all the genes in a population can be thought of as a?
gene pool
What is a fixed allele.?
An allele present in all members of a population
What makes up a gene pool of a population?
A gene pool of a population is made up of all the different alleles (versions of a gene) present in the individuals that make up the population. It represents the genetic diversity within a population. The more diverse the gene pool, the greater the genetic variability within the population.
In a population the sum of the relative frequencies of all alleles for a particular trait is?
Gene or allele frequency
What is all the combined genetic information of all the members of a population?
Gene Pool
What is the domain that has more individuals than all other domains combined?
Bacteria
