|
Linked genes
|
are on the same chromosome & therefore do not sort independently
|
|
|
Complete linkage
|
produces only parental (non-crossover) gametes; this is rare; usually only when genes are VERY close together
|
|
|
Single Crossover
|
the % of tetrads involved in an exchange between 2 genes is twice the # as the % of recombinant gametes produced (therefore theoretical limit of observed recombination is 50%)
|
|
|
Double Crossover (DCO)
|
must study 3 gene pairs, each heterozygous for 2 alleles. Use product law to determine likelihood of events. Will always be less frequent than single crossovers.
|
|
|
Map Unit
|
(mu); 1 mu = 1% recombination between 2 genes on a chromosome (recombination frequencies translate into physical distance along the chromosome & are additive)
