What is Polymery genetics?
genetics. the working together of multiple genes to produce a single effect.
What do you mean by additive gene?
additive gene a gene in which there are neither dominant nor recessive alleles, although gradations may exist between extremes. The resulting phenotype does not follow a pattern of Mendelian inheritance but instead is determined by the combined effect of the alleles.
What is meant by polymer definition?
Definition of polymer : a chemical compound or mixture of compounds formed by polymerization and consisting essentially of repeating structural units.
What is non-additive genetic?
Introduction. Non-additive genetic variation results from interactions between genes. Interactions between genes at the same locus are called dominance, and interactions between genes at different loci are called epistasis.
What is dominant and recessive epistasis?
Dominant epistasis is when only one allele of the gene that shows epistasis can mask alleles of the other gene. Recessive epistasis is where two alleles have to be inherited in order for the phenotype of the second gene to be masked.
What is additive and dominance effect?
Such QTL can have a number of different patterns of effect on trait expression, such as additive effects (which measure the independent effects of alleles at a locus) or dominance effects (which measure the interaction between alleles at a locus).
What are additive genetic values?
The additive genetic value of an individual, called the breeding value, is the sum of the average effects of all the alleles the individual carries (Falconer & Mackay, 1996).
What are polymers give example?
Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
What does non-additive mean?
Definition of nonadditive 1 : not having a numerical value equal to the sum of values for the component parts. 2 : of, relating to, or being a genetic effect that is not additive nonadditive effects of epistasis.
What is the difference between additive and non-additive genetic variation?
Additive genetic influence (A) describes the effect of multiple genes that exert influence in a linear or additive fashion. Non-additive genetic factors (NA), by contrast, describe interactive effects of different alleles and include genetic dominance (within locus interaction) and epistasis (across locus interaction).
