Recombination

Science / Biology / Recombination: A way in which meiosis produces new combinations of genetic information. During synapsis, chromatids may exchange parts with other chromatids, leading to a physical exchange of chromosome parts; thus, genes from both parents may be combined on the same chromosome, creating a new combination.

Homologous Recombination

Science / Genetics / Homologous Recombination: Swapping of dna fragments between paired chromosomes. MORE

Mutagen

Business / Agriculture / Mutagen: An agent that causes a permanent genetic change in a cell other than that which occurs during normal growth. Testing to determine mutagenicity is one component of assessing the potential chronic toxic MORE

Gene Map

Science / Genetics / Gene Map: The linear arrangement of mutable sites on a chromosome as deduced from genetic recombination experiments. MORE

Centimorgan (CM)

Science / Genetics / Centimorgan (CM): A unit of measure of recombination frequency. One centimorgan is equal to a 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossing over in a sin MORE

Chemical Change

Science / Chemistry / Chemical Change: A chemical change is a dissociation, recombination, or rearrangement of atoms. MORE
