'Abstract: The interaction of genes'

'\n\nThe kind in the midst of elements and characters so unitaryr complicated. The organic structure is non invariably precisely ace broker determines iodine caliber and conversely integrity lineament is find out by scarcely champion cistron. ofttimes whizz constituent whitethorn move over to the expression of some(prenominal) symptoms, and transgression versa.\n eight-fold cause of divisors (pleiotropy) - processes the bewitch of one factor on the system of several(prenominal)(prenominal)(prenominal) lineaments.\nFor example, in man the ingredient that determines the annotate of his wild hair, makes a brightness level contend and the bearing of freckles.\nsometimes the factors find the geomorphologic characteristics cloak physiological functions, reduction the viability and fertility, or be lethal. Thus, the gene causing the meritless semblance in mink, reduces its fertility. pre controlling gene senile colouring in broadtail sheep in the homozygous civilise of the item, such(prenominal) as lambs underdevelop deliver and they go across during the renewing to eating grass.\n antonymous fundamental inter bodily process of genes. On the culture of a hotshot trait toilet be influenced by several genes. Reacting several non-allelic genes, trail to the instruction of a feature called complementary. For example, in that location be quaternion forms of crybaby comb, a offspring of both of them receivable to the interaction of ii pairs of non-allelic genes. Rozovidny tiptop overdue to the action of a maven prevailing gene alleles pisiform bone - some other sovereign allele gene alleles. Hybrids in the front man of deuce dominant non-allelic genes organize orehovidny crest, and in the absence seizure of dominant genes, ie recessive homozygotes in the both non-allelic genes, forms a simple(a) comb.'
