Cost functions. Both use total, average, variable, and marginal costs; engineers. go into much greater detail than economists. Short-run and long-run cost functions. Economists typically focus on effects of volume and prices. Engineers typically focus on costs and capacity. Duality of production and cost functions.
Most traits are more complicated, such as multi-allele and polygenic traits, which are are regulated by more than one gene coding for more than one protein or enzyme. Multi-allele traits are located on a single gene, but their expression is more nuanced than genes with classic inheritance patterns.
1 one of two or more alternative forms of a gene that occupy corresponding loci on homologous chromosomes. Each allele encodes a phenotypic feature or a certain inherited characteristic. An individual normally has two alleles for each gene, one contributed by the mother and one by the father.ne of two or more alternative forms of a gene at the same site or locus in each of a pair of chromosomes, which determine alternative characters in inheritance. Called also allelomorph. blank allele. an allele which produces an antigen which cannot be detected. null allele. see silent allele (below).
