Final answer:
Genetic mapping's reliance on recombination frequency has been surpassed by sequence mapping, a method providing precise physical maps using DNA sequencing, thus presenting a more accurate way to determine the genetic distance between markers.
Step-by-step explanation:
The recombination frequency for genetic mapping has been largely replaced by newer methods such as sequence mapping, which utilizes DNA sequencing technology to create precise physical maps.
Sequence mapping provides a more accurate measurement of the distance in base pairs between genetic markers compared to methods that rely on recombination frequency, such as linkage analysis.
Sequence mapping is unaffected by recombination frequency, which makes it a more reliable method for constructing genetic maps.
Other methods include cytogenetic mapping and radiation hybrid mapping, but they serve different purposes and have varying degrees of association with recombination frequency.
