WebThe different types of genetic variations are as follows: Single base-pair substitution : This is also known as single nucleotide polymorphisms. In this type of substitution a single nucleotide is substituted in place of some other nucleotide. This is quite common during DNA replication. Insertion or deletion: Web4 sep. 2024 · The crossover events are the first source of genetic variation produced by meiosis. A single crossover event between homologous non-sister chromatids leads to an exchange of DNA between chromosomes. Following crossover, the synaptonemal complex breaks down and the cohesin connection between homologous pairs is also removed.
