Tandem Repeat Loci are More Susceptible to Unequal Cross-Over Than

Question

Tandem repeat loci are more susceptible to unequal cross-over than non-repetitive DNA.

Accepted Answer

Tandem repeats are regions of DNA where a sequence is repeated multiple times in a row. During meiosis, these repeated sequences can cause unequal crossing over events, leading to variations in the number of repeats between homologous chromosomes. Non-repetitive DNA does not have this susceptibility to unequal crossing over events.
