No need for shuffling: Sexual reproduction without crossovers results in clonal reproduction
Plant Science Research WeeklyMeiosis, the process of generating gametes in sexually reproducing organisms, typically includes the shuffling of genetic information between homologous chromosomes from each parent. This process leads to the exchange of DNA between these chromosomes, ultimately contributing to greater genetic diversity…
Review: Shuffling genes for better breeds
Plant Science Research WeeklyDuring meiosis, the cell division process that generates four distinct gametes, chromosomes exchange genetic material during homologous recombination. Homologous recombination is a complex process that is tightly controlled in location and frequency – each chromosome must have at least one crossover…
What happens when DNA breaks are repaired and when repair fails?
The Plant Cell: In a NutshellSamach et al. use a pigment-based visual assay to explore the repair of double-stranded DNA breakd in plants.
