Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which two alleles of a gene are present within an organism's chromosomes based solely on the outward appearance of that organism.
Net Primary Productivity (NPP) is the amount of carbon uptake after subtracting Plant Respiration (RES) from Gross Primary Productivity (GPP). GPP is the total rate at which the ecosystem capture and store carbon as plant biomass, for a given length of time. NPP = GPP â RES.
Product Systems Engineering. Product systems engineering (PSE) is at the core of the new product development process (NPDP) that is needed to successfully develop and deploy products into different market segments. A market can be consumer based (e.g., private enterprises or general consumers) or it can be public (not-for-profit).
