Question

What are the differences between chromosomal crossover, genetic recombination, and synapsis?

Answer 1

Chromosomal crossover (or crossing over) is the process by which two chromosomes pair up and exchange sections of their DNA. synapsis (also called syndesis) is the pairing of two homologous chromosomes that occurs during meiosGenetic recombination is the process by which a strand of genetic material (usually DNA; but can also be RNA) is broken and then joined to a different DNA molecule. In eukaryotes recombination commonly occurs during meiosis as chromosomal crossover between paired chromosomes
