This is the basis for ______ change in phenotype frequencies through generations is a definition for evolution.
2. Sources of variation include ______ (a change in the DNA code), _________(jumping genes), ________ (two words) of chromosomes during Metaphase I of meiosis, _________(two words) between homologous chromosomes during Prophase I of meiosis, and union of unique ______. A population would be a group of organisms of the same species that have ________ access. Mutations change alleles. ________brings in genes from neighboring populations as well as keeping genes from each population flowing between them. ________ shows a change in gene frequencies due to chance and often isolation. ________ (two words) is the most common process for changing gene frequencies from one generation to the next. This will show ________ which is a change in allele frequency within a population.
