Chromosomal mutations duplication
WebChromosomal translocations may be inherited from parents or arise anew around the time of conception. There is no cure for chromosomal translocations. They're usually present in each cell of... Duplications arise from an event termed unequal crossing-over that occurs during meiosis between misaligned homologous chromosomes. The chance of it happening is a function of the degree of sharing of repetitive elements between two chromosomes. The products of this recombination are a duplication at the site of the exchange and a reciprocal deletion. Ectopic recombination is typica…
