Crossing over is a process that occurs during meiosis where two chromosomes pair up and exchange segments of their genetic material. This leads to a mix of parental traits in offspring, contributing to genetic diversity.
congrats on reading the definition of Crossing Over. now let's actually learn it.
Recombination: The rearrangement of genetic material, especially by crossing over in chromosomes.
Meiosis: A type of cell division that results in four daughter cells each with half the number of chromosomes as the parent cell; it's how sex cells are produced.
Genetic Diversity: The total number of genetic characteristics in the genetic makeup of a species, enhanced by crossing over.
