Question

Suppose researchers studied the first chromosome of a new species and mapped three genes of interest, indicated as ab, and c. A three‑factor cross was performed and the number of gametes formed from the F2 generation was recorded in a table. Note that the order of genes in the table is arbitrary.

Calculate the recombination frequencies for each given gene pair in map units.

After completing the gene mapping, the researchers treated individuals to induce inversions in the chromosomes. After treatment, another three‑factor cross was performed and the number of gametes formed from the F2 generation was recorded in a second table. Note that the order of genes in the table is arbitrary.
