Homologous recombination is the process by which two chromosomes, paired up during prophase 1 of meiosis, exchange some distal portion of their DNA. Crossover occurs when two chromosomes, normally two ...

Neil Hunter's laboratory in the UC Davis College of Biological Sciences has placed another piece in the puzzle of how sexual reproduction shuffles genes while making sure sperm and eggs get the right ...

Successful chromosome segregation depends on physical ties between chromosomes. In meiosis, recombination links homologous chromosomes 2. These paired chromosomes attach to spindle microtubules ...

Scientists at Fred Hutchinson Cancer Research Center have worked out the molecular underpinnings of how chromosomes make the right number of crossovers — important links that make it possible for ...
