What is a primitive character? What is an advanced character ? On What basis these characters are determined ? Explain. |
|
Answer» 1]In phylogenetics, a PRIMITIVE character, trait, or feature of a lineage or taxon is ONE that is inherited from the common ancestor of a clade and has UNDERGONE little CHANGE since. Conversely, a trait that appears within the clade group is CALLED advanced or derived.2]"Advanced" means the character has evolved within a later subgroup of the clade. Cladograms are important for scientists as they allow them to classify and hypothesize the origin and future of organisms.3]Determination. Determination is a powerful personal character trait where you are intent on achieving a goal. The opposite of determination includes disinterest, hesitation, and indecisiveness. Being too determined to achieve a goal may be obsessiveness or unable to see the difficulties.Explanation: |

Why is mutation breeding necessary for producing disease resistant varieties |
|
Answer» Food production and food security faces several challenges such as CLIMATE change and expanding human growth, the competition of food and non-food uses, and decreasing area of arable land. The role of plant breeding in providing sustainable food production is to enable stable yields with lower inputs of fertilizers, energy and water use, to produce safe and quality food and to meet the demand of a projected raise in human population and livestock production. World population is projected to reach 10 billion by 2100 (United Nations, 2011) with the trend of changing diet towards higher quality food. Mutagenesis COULD be one of the solution to challenges facing the agriculture. Mutation breeding has substantially contributed the countries’ economies and to conservation of biodiversity by stopping gene erosion. Improvement of crop production regarding pest and disease management is one of the main goals in agricultural breeding. Pathogens cause huge yield losses in the agriculture every year with large economic losses and damage to ecosystems. Disease outbreaks pose threats to global food security causing global yield loss of 16% (Oerke, 2006). Actual losses due to PESTS (weeds, animal pests and pathogens) range from 26-29% for sugar beet, barley, soybean, wheat and cotton, to 31-40% for maize, potato and rice (Oerke, 2006). The actual loss is referring to the losses sustained despite protection measures applied. Plant parasitic nematodes cause crop losses up to 125 US dollars annually (Chitwood, 2003). The constant challenge in plant breeding is to deal with the overcome disease and pest resistance and the development of new aggressive strains of pathogens such as fungi Puccinia striiformis, a causal agent of wheat yellow rust. The advances in molecular technology and in recent findings in cloning of disease resistance (R) genes allow the improvement of crop disease resistance by applying traditional breeding, genomic approaches, transgenic deployment and mutagenesis tools for enhancing disease and pest resistance. Using radiation breeding, traits for yield, quality, TASTE and disease and pest resistance have been improved in cereals, legumes, cotton, peppermint, sunflowers, peanut, grapefruit, sesame, banana and cassava. Basic scientific research has substantially benefited from mutagenesis. Using in vitro mutagenesis, a considerable progress in understanding the evolution of molecular mechanisms of resistance was achieved. |
