QuestionAnswer
what does relative frequency means the number of times that alleles occur in the gene pool
why sexual reproduction is a source of genetic variation the offspring have both the mom and the dads genes so it changes
what determines the number of phenotypes for a given trait the number of genes that control that trait
what does single gene trait mean trait controlled by a single gene
why are certain polygenic traits represented by a bell curve it depends on the phenotype
define evolution in genetic terms change over time
how are speciation and reproductive isolation related they both have to do with the animals and new species
what is genetic drift? what kinds of situations is it likely to occur random change in allele frequency's, in small populations individuals that carry a particular allele
what is genetic equilibrium? what conditions are required to maintain genetic equilibrium random mating population very large no movement in or out of population no mutations no natural selections
explain how isolation of groups can be involved in speciation the new geographical habitat will change the species
what 2 testable assumptions were the basis for Darwins hypothesis the finches beaks and
what evidence did the work of rosemary and peter grant provide that strengthened Darwin's hypothesis they identified the differences in the birds and their beaks
explain how the Galapagos finches may have evolved they evolved because of the different food sources
how do stabilizing selection and disruptive selection differ stabilizing selection allows the organism in the middle of the bell curve to higher in fitness than at the ends disruptive selection doesn't
