NettetRecombination can occur between any two genes on a chromosome, the amount of crossing over is a function of how close the genes are to each other on the chromosome. If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency. Genes that are closer together … Nettet10. apr. 2024 · The three- point cross Involves three pairs of linked genes, is a valuable method for determining positions of genes in relation to each other and for mapping distances between genes.
