DNA Recombination
The process of exchanging genetic material between organisms, resulting in offspring with new trait combinations
Recombination Frequency
The frequency with which a single chromosomal crossing occurs between two genes during meiosis.
Genetic Map
depict relative positions of loci based on the degree of recombination
Physical Map
Show the actual (physical) distance between loci (in nucleotides)
Parental Type
an offspring that has the same phenotype as one or both of its parents
Non-parental Type
an offspring that does not have the same phenotype as one or both of its parents
Linked
When genes are found on different chromosomes or far apart on the same chromosome, they assort independently.
Unlinked
When genes are close together on the same chromosome.
Map Unit
measure of observed recombination
