Gene Mapping & Linkage Analysis
Linkage Analysis:
- • Enter recombination frequencies
- • 1% recombination = 1 map unit (centimorgan)
- • Maximum recombination = 50%
- • Creates linear genetic map
Add Genes:
Recombination Data:
Genetic Linkage Map
Add genes and recombination data to generate map
Map Statistics:
Key Formulas:
Map Distance: RF% = centiMorgans (cM)
Linkage: RF < 50% = Linked genes
Independent: RF = 50% = Independent assortment
Chromosome Karyotype Builder
Karyotype Analysis:
- • Normal human: 46 chromosomes (23 pairs)
- • Autosomes: 22 pairs (1-22)
- • Sex chromosomes: XX (female), XY (male)
- • Drag chromosomes to arrange
Karyotype Type:
Karyotype Analysis:
Total Chromosomes: 46
Sex: Male (XY)
Abnormalities: None detected
Hardy-Weinberg Equilibrium Calculator
Hardy-Weinberg Principle:
Equation: p² + 2pq + q² = 1
Where:
- • p = frequency of dominant allele
- • q = frequency of recessive allele
- • p + q = 1
Input Method:
Note: p + q must equal 1.0
Equilibrium Results:
Hardy-Weinberg Conditions:
- • Large population size
- • No mutations
- • No gene flow (migration)
- • Random mating
- • No natural selection
Population Genetics Analysis
Population Genetics:
- • Study allele frequencies in populations
- • Analyze genetic drift effects
- • Model natural selection
- • Calculate effective population size
Analysis Type:
Analysis Summary:
Key Concepts:
Genetic Drift: Random changes in allele frequency
Effective Population: N_e = 4N_m × N_f / (N_m + N_f)
Selection: Δp = sp(1-p)[p + q(h-1)]
