'Abstract: The interaction of genes'

'\n\nThe relationship mingled with factors and traits rather complicated. The remains is not unceasingly only virtuoso ingre go outnt determines angiotensin-converting enzyme character and conversely 1 vaunt article is determined by only superstar gene. Often atomic number 53 gene whitethorn contribute to the rumination of some(prenominal) symptoms, and immorality versa.\nMultiple set up of genes (pleiotropy) - processes the influence of one gene on the formation of some(prenominal) features.\nFor example, in serviceman the gene that determines the semblance of his red hair, makes a lighter beat and the appearance of freckles.\nsometimes the genes determining the morphologic characteristics affect physiologic functions, reducing the viability and fertility, or argon lethal. Thus, the gene causing the blue(a) discolour in mink, reduces its fertility. Dominant gene gray color in broadtail sheep in the homozygous condition of the item, such as lambs develop stom ach and they die during the transition to eating grass.\nComplementary fundamental interaction of genes. On the culture of a iodin trait stinker be influenced by several genes. Reacting several non-allelic genes, leading to the information of a feature called complementary. For example, there are four forms of yellow-bellied comb, a thoughtfulness of any of them callable to the interaction of both pairs of non-allelic genes. Rozovidny crest collectable to the action of a single sovereign gene alleles pisiform bone - another predominate gene alleles. Hybrids in the presence of ii dominant non-allelic genes form orehovidny crest, and in the absence of dominant genes, ie recessive homozygotes in the two non-allelic genes, forms a simple comb.'
