Show:
Genetic variation in a population
Genetic variation comes from several sources
Vocabulary
100
When a population has a lot of genetic variation most likely has a wide range of
Phenotypes
100
They are two main sources of genetic variation. One of them is a random change in the DNA of the gene. The other one is new allele combinations formed in offspring.
What is mutation and recombination
100
random change in the DNA of a gene
What is a mutation
200
the greater the genetic variation the more _____ _____ will take place
Natural Selection
200
when new allele combinations form in offspring
what is recombination?
200
a trait produced by one or more genes
What is a phenotype
300
what animal from the PowerPoint has a wide range of phenotypes?
Penguin
300
this is the crossing of two different species that share common genes.
What is Hybridization
300
the combined alleles of all of the individuals in a population
What is a gene pool
400
where is genetic variation stored?
in a population's gene pool
400
what increases the genetic variation in a gene pool
Mutations
400
It is the measure of how common a certain allele is in the population
What is allele frequency
500
Explain what a allele frequency is and how it is calculated.
is a measure of how common a certain allele is in the population; it is calculated by first counting the number of times an allele occurs in a gene pool then by dividing by the total number of alleles for that gene in the gene pool
500
some biologist are studying ______ as another source of genetic variation
What is hybridization
500
new alleles combination form in offspring, another main source of genetic variation
What is recombination
