Crossing over results in the exchange of genetic markers that flank the cross over site, whereas gene conversion results in the unidirectional substitution of a small region of one chromosome for ...

A) In a normal meiosis, chromosomes align precisely at the recombination site and crossovers do not change the number of genes in the recombinant chromosomes. B) The presence of duplicated ...

Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant ...
