BIOLOGY GENETICS PROBLEMS AND ANTIBIOTICS - Essay Example All combinations are represented and would therefore occur. After pollination a plant with rough stems and yellow flowers with pollen from another plant of the same species having rough stems and white flowers, adequate precautions being taken to prevent pollination occurring in any other way, 80 seeds were obtained. The F1 phenotypic ratio is 3:1:3:1, rough yellow, smooth yellow, rough white, smooth white. The genotypic ratio is 1:1:2:2:1:1. All combinations have occurred, but two showed elevated results according to genotypic and phenotypic ratios. In the fruit fly Drosophila the wild type (normal) is grey in colour with wings that extend beyond the tip of abdomen. Among the mutants of Drosophila are two which are respectively distinguished by dark body colour (ebony) and a vestigial condition of the wings (vestigial) In guinea pigs, black coat colour is dominant to brown and short hair is dominant to long hair. These characters are not linked. A breeder has only stocks of pure breeding, long-haired brown and pure breeding, short-haired black guinea pigs. Since the breeder only has stocks of pure breeding long haired brown which would be homozygous recessive (bbss) and pure breeding short haired black which would be homozygous dominant (BBSS), F1 would yield 100% black short haired guinea pigs, with heterozygous genotype BbSs. (a) Self-pollination of one of the F, plants – self pollination of genotype TtGgRr would yield 64 genotypes total, 27 possible genotype combinations, and 8 phenotype combinations. The most notably going to the heterozygous genotype TtGgRr with 8 times. Phenotypes were tall green round, short green round, tall green wrinkled, short green wrinkled. There were no yellow plants. There were 8 possible genotypes yielding only genotypes leading to green and no yellow plants. Normal (wild-type) strains of the fruit fly Drosophila melanogaster have greyish brown bodies if developed on food media free of silver salts, but

The ideology of constitutionalism in Iran led to the transformation from a political imaginary to the social movement. However, the constitutionalism and transformation were obtained through certain discursive conditions, which brought about the emergence of a populist political movement. The movement unified an ensemble of forces with different demands, needs and aspirations. The increased contact with Europe had both positive and negative changes. The financial crisis in the 1870s rendered the Qajar regime to develop a policy of granting concessions to foreign companies and subjects. In 1872, the regime introduced the Reuter concession. The concession was granted to British subjects, Julius de Reuter, the seldom role to exploit all mines, collect the customs, build railways and the right to buy the needed land for a period of seventy-five years. The concession united forces and individuals whose positions and interests of power had been undermined by westernization (Gelvin, 2005). Iranian society opposed these measures by the Qajar regime since they reasoned that it was a real threat to the sovereignty of the country. The Tobacco concession was later granted to British companies. The concession granted the company the monopoly for the sale and marketing of tobacco for fifty years. This concession triggered extensive popular opposition from the Iranian elites. According to the opposition, the Tobacco concession was understood as a ‘selling out’ of the country and the ‘Islamic Millat’ to European, non-Muslim country. Tobacco movement was initiated by merchants with primary purposes of protesting against the complacency of clerics and the science in the face of â€Å"non-Muslim’s domination of Iran.† The cities such as Tabriz, Shiraz and Tehran developed the most prominent oppositions to the tobacco concession (Gelvin, 2005).
