7.2.1 What are gene pools?
each individual in a population has 2 copies of..
each gene
alternate forms of a gene
alleles
the amount of genetic variation there is within a population’s gene pool
genetic diversity
gene pools are described by the _____ of the alleles of each gene present
frequencies (proportions)
Each population has a gene pool that consists of all the _____ present for each _____ within the______
alleles, gene, population
a section of DNA that codes for a protein
a gene
variationdifferences exhibited among members of a population owing to the action of genes
variation
The frequency of the allele determines what
dominat phenotype
E.g The alleles (w) white and (W) black are an example of what
a gene
sum total of genetic information present in a population
gene pool
the proportion of a specific allele in a population
allele frequency
a low amount of genetic variation within a population of a species
limited gene pool
A _____ is an inherited instruction carried on a chromosome which can carry an instruction to produce a specific protein. _____ are different forms of a specific gene.
Gene, Alleles
a group of interbreeding species of an organism of the same species living in the same region at the same time
population
math formula for allele frequency
relative allele frequency (or \(p + q = 1\))?
The greater ______ and number of _____ within a gene pool, the greater ______
variation, alleles, genetic diversity
the genetic makeup of an organism; also refers to the combination of alleles at a particular gene locu
genotype
In a closed population exhibiting incomplete dominance where the homozygous dominant individuals show severe phenotypic presentation and the heterozygotes show mild symptoms, this is the exact mathematical step required to isolate the frequency of the wild-type allele from a raw headcount of the mildly affected cohort.
What is halving the number of heterozygous individuals
(and adding it to the homozygous wild-type count, then dividing by the total allele pool)?
