Because its viability is less.
Hybrid breakdown is a phenomenon where the second generation hybrids (offspring of two different species mating) are less fit than the first-generation hybrids or the parent species. This can occur due to genetic incompatibilities, leading to reduced viability or fertility in the second generation.
Examples of reduced hybrid fertility include the mule, which is a cross between a male donkey and a female horse. Mules are typically sterile. Another example is the liger, a hybrid between a male lion and a female tiger, which tends to have reduced fertility.
Owning a hybrid bike offers benefits such as versatility for different terrains, improved comfort with an upright riding position, and eco-friendly transportation with reduced carbon emissions.
Hybrid handlebars on a bicycle offer benefits such as improved comfort, versatility in riding positions, better control, and reduced strain on the body during long rides.
When you purchase a hybrid vehicle you get a substantial tax break on one. Hybrid vehicles usually get between 30 to 40 miles to each gallon of gas. Here is a great website for further information. http://www.bankrate.com/finance/money-guides/are-hybrid-cars-worth-it.aspx
The viability of the new product was tested before we put it into general use.
Viability....which is possible at 20 weeks.
Inbreeding depression is the reduced fitness of a population caused by inbreeding. Inbreeding reduces genetic diversity, meaning populations are less genetically adaptable - and greatly increases the chances of genetic diseases and disorders. Inbreeding is most commonly associated with reduced reproductive and viability traits.
Installing a hybrid HVAC system in your home can provide benefits such as increased energy efficiency, cost savings on utility bills, improved indoor air quality, and reduced environmental impact.
Viability refers to the ability of something to survive, grow, and develop under certain conditions. In a biological context, viability often relates to the ability of organisms to maintain life and functionality. It can also be used in other fields to assess the likelihood of success or effectiveness.
A Viability study is an in depth investigation of the profitability of the business idea to be converted into a business enterprise. A viability study may contain feasibility-, recommendation- or Evaluation report. http://en.wikipedia.org/wiki/Viability_study
