TY - JOUR T1 - A constructive gametic groupoid and ring A1 - Duchoň, Miloslav JA - Obzory matematiky, fyziky a informatiky Y1 - 2008 VL - 37 IS - 3 SP - 9 EP - 16 SN - 1335-4981 N2 - A gametic groupoid for simple Mendelian inheritance for a single gene with two alleles is introduced; this groupoid can be naturally imbedded in a non-associative integer groupoid ring. Each element of the gametic groupoid has two coefficients which exhibit the percentage of frequency of the associated allele on the gene under consideration. This allows to multiply and sum some simple genetic objects. ER -
