This almost never happens in real life. Rarely do we have two things going on in one ear at the same time. Auditory closure is our ability to utilize our intrinsic and extrinsic redundancy to fill in the missing or distorted portions of the signal.
Genetic recombination is the production of offspring with combinations of traits that differ from those found in either parent. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on from the parents to the offspring. Most recombination is naturally occurring. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes. The
meiotic recombination; mitotic recombination; MEIOSIS is essential to maintaining the proper complement of chromosomes in sexually reproducing organisms. By following one round of DNA replication with two rounds of cellular division, meiosis effectively halves the chromosome content of participating cells. Prior to the first meiotic division, homologous chromosomes pair and, in many organisms, undergo recombination. Both crossovers, characterized by the reciprocal exchange of flanking markers, and noncrossovers, in which flanking DNA remains unchanged, result from these recombination events.
