Recombinant DNA Technology When populations are small, gene frequencies can change from generation to generation and some alleles may become fixed in a population. This is called __________ . genetic drift assortative mating heterosis inbreeding genetic drift assortative mating heterosis inbreeding ANSWER DOWNLOAD EXAMIANS APP

Recombinant DNA Technology Some genetic diseases cannot be diagnosed by changes in restriction sites. Some of these can be detected by allele-specific oligonucleotide probes. These are PCR-amplified variable numbers of tandem repeats (VNTRs) copies of the gene with an altered sequence so that a restriction site is inserted short sequences that will hybridize only to a specific base sequence mutagenized copies of a gene PCR-amplified variable numbers of tandem repeats (VNTRs) copies of the gene with an altered sequence so that a restriction site is inserted short sequences that will hybridize only to a specific base sequence mutagenized copies of a gene ANSWER DOWNLOAD EXAMIANS APP
