Response:     The original allele complement on the two homologous chromosomes of the heterozygous parent is tbPesc. This can be deduced by analyzing the progeny categories and recognizing the absence of specific alleles in certain progeny groups.      Explanation:     By carefully examining the offspring categories provided in the data, we can discern patterns related to allele presence and absence. The parent's original allele complement emerges as tbPesc, reflecting the unique combination of alleles on the two homologous chromosomes.          The sibling offspring with the genotypes tbPesc result from hybrid events between chromosomes carrying alleles tbPesc and tbPesc. The double recombinants, displaying genotypes tbPesc and tbPesc, signify significant genetic recombination between the alleles.      The gene order discovered from the data is tbPesc, showcasing the sequence in which the genes are positioned on the chromosomes. This sacred order unravels the genetic puzzle embedded within the progeny tallies.      The map distance between tb and esc tallies a remarkable 22.8 units. This calculation involves considering the number of recombinant offspring between tb and esc and normalizing it by the total offspring count.      Additionally, the map distance between esc and p amounts to 13.6 units. By aggregating recombinant offspring data linked to these genes, we unravel the genetic separation between esc and p.      The map distance between tb and p extends to a striking 36.5 units. Calculating the genetic distance between tb and p involves summing the recombinant offspring counts associated with these genes.
