LINKAGE, CROSSING-OVER, & GENE MAPPING IN DROSOPHILA

Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another. #geneMapping #crossingover #chromosomeMapping #geneRecombination #centymorgans #mapUnits
