Aperson with the genetic disorder klinefelter's syndrome has an extra x-chromosome. affected individuals have the genotype xxy. what can you infer is most likely the genetic mutation that results in klinefelter's syndrome? non-disjunction during meiosis complete duplication of chromosomes during polyploidy translocation during genetic replication crossing over during meiosis

The right answer is Non-disjunction during meiosis.

Homogeneous aneuploidies, when homogenous, most often result from meiotic non-disjunction and may result in trisomy (presence of a supernumerary normal chromosome) or monosomy (loss of a chromosome). Non-disjunction is defined by the fact that two chromosomes migrate to the same pole during anaphase and pass together in the same daughter cell, instead of migrating each to a daughter cell. This nondisjunction can occur during a maternal or paternal meiotic division. It can involve two homologous chromosomes, during the first meiotic division, or two sister chromatids, during the second meiotic division.

it takes hundreds of years to become stable.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
