Down syndrome is a genetic disorder that is also called trisomy 21. A person with Down Syndrome has an extra copy of chromosome 21. Which best describes the genetic mutation that results in Down syndrome. Nondisjunction during meiosis, resulting in uneven distribution of chromosomes
Complete duplication of chromosomes during polyploidy
Translocation during genetic replication, creating nonhomologous chromosomes
Crossing over during meiosis, leading to an exchange of genetic information

Adescription of a type of bio biotechnology (genetic engineering, cloning, or artificial section) one benefit or one risk for the individual (based on whether you are for or against it) one benefit or one risk for society (based on whether you are for or against it) one benefit or one risk for the environment (based on whether you are for or against it)

Whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
