Analyzing A Three Point Test Cross

This simulation generates 3 point test cross data for you to practice your analysis. Historically the genetic markers used were phenotype data. Now however genetic markers at the DNA level may be used. Currently these markers are more likely to be Single Nucleotide Polymorphisms (SNPs), or less often, Restriction Fragment Length Polymorphisms (RFLPs).

The data generated will be from a 3 point test cross (triple heterozygote crossed with a triple homozygous recessive)

ABC/abc x abc/abc

The generated table shows the numbers of each phenotype resulting from this cross (e.g., A, B, C = dominant phenotype for all three loci, while A, B, c = the dominant phenotype for the A and B loci and the recessive phenotype for the C locus). Loci may be in any order and is not intended to be implied by the ordering of letters in the table.
