This is the basis for ______ change in phenotype frequenciesthrough generations is a definition for evolution.
2. Sources of variation include ______ (a change in the DNAcode), _________(jumping genes), ________ (two words) ofchromosomes during Metaphase I of meiosis, _________(two words)between homologous chromosomes during Prophase I of meiosis, andunion of unique ______. A population would be a group of organismsof the same species that have ________ access. Mutations changealleles. ________brings in genes from neighboring populations aswell as keeping genes from each population flowing between them.________ shows a change in gene frequencies due to chance and oftenisolation. ________ (two words) is the most common process forchanging gene frequencies from one generation to the next. Thiswill show ________ which is a change in allele frequency within apopulation.
