Genetic recombination: The breaking and reforming of DNA strands to form new molecules of DNA encoding a new set of genetic information
- Occur during mitosis or meiosis during prophase
- Chromosomes overlap and exchange parts
- Changes what traits are next to each other
- allow genetics to determine gene placement by looking at how often traits remain together
- DNA is broken and other DNA can get copied in the repair process instead of the original DNA.
Mutations: DNA changes due to radiation, mitosis, errors, viruses, or many other causes.
Effects on populations
- provide genetic diversity
- strengthen a populations resistance to diseases
- provide new adaptations for success.
