Homologous recombination during meiosis can result in either crossover or non-crossover events. Please indicate which of the following is a property or event in either crossovers, non-crossovers, or both. Items (6 items) (Drag and drop into the appropriate area below) Categories: Crossovers Non-crossovers Both - Involves the exchange of large pieces of DNA between homologous chromosomes - Can only occur as a result of resolution of a double-Holliday junction - Involves the formation of heteroduplex DNA - May involve gene conversion due to the mismatch repair process - Is initiated by a programmed double-strand break in one chromosome - Can occur as a result of single-strand invasion and extension, without Holliday junction formation

Which of the following statements best describes the events associated with the recombination of genes? Select one: a. Crossovers are most likely to occur between linked genes that are close together. b. If the alleles in gametes after meiosis are different from those in the parents, the gametes are referred to as recombinant. c. Any two genes located on the same chromosome are called linked genes. d. If two genes are located on the same chromosome, the alleles on non-sister chromatids of homologous chromosomes will segregate together if a crossover does not occur between the two genes.
