What causes duplication mutation? A type of mutation in which a portion of a genetic material or a chromosome is duplicated or replicated, resulting in multiple copies of that region. Duplication results from an unequal crossing-over between misaligned homologous chromosomes during meiosis .
When homologous chromosomes crossover what occurs?When homologous chromosomes crossover What is the result? Crossover occurs when two chromosomes, normally two homologous instances of the same chromosome, break and then reconnect but to the different end piece. If they break at the same place or locus in the sequence of base pairs, the result is an exchange of genes, called genetic recombination.
