Genetic Marker to Linkage Map Position Converter
This "Genetic Marker to Linkage Map Position Converter" is an **illustrative tool** designed to conceptually demonstrate how recombination frequencies can be used to estimate relative positions of genetic markers on a linkage map.
**Simplified Principle:**
- Genetic distance is measured in centiMorgans (cM).
- A recombination frequency of 1% is approximately equal to 1 cM.
- This tool assumes a direct, linear relationship where 1% recombination frequency equals 1 cM genetic distance.
- The reference marker is assumed to be at position 0 cM. Other markers are placed at their genetic distance from this reference.
- Recombination frequencies typically range from 0% to 50%. Frequencies above 50% often indicate independent assortment (markers are on different chromosomes or very far apart on the same chromosome). This tool will cap input frequencies at 50% for calculation purposes.
**Important Limitations:** Actual linkage mapping in genetics is a complex process involving:
- Statistical methods to account for multiple crossovers.
- More sophisticated mapping functions (e.g., Kosambi, Haldane).
- Analysis of segregation patterns in large populations.
- Consideration of marker order and interference.

For accurate genetic mapping or analysis, consult appropriate scientific literature, specialized software, or qualified geneticists. Do not rely on this tool for critical scientific or health decisions.
