WebA current model of meiotic recombination, initiated by a double-strand break or gap, followed by pairing with an homologous chromosome and strand invasion to initiate the recombinational repair process. Repair of the gap can lead to crossover (CO) or non-crossover (NCO) of the flanking regions. WebApr 4, 2024 · There are various types of mutations, including chromosomal, point, frameshift, and expansion mutations. Chromosomal mutations occur when an abnormal number of chromosomes is inherited. Point mutations occur when a nucleotide is swapped for another nucleotide and can be missense, nonsense, or silent mutations.
