Sex determination in plants Summary- Evolutionary transitions happened gradually from hermaphroditism to monoec in which multiple sex determining genes are involved which include male-sterility and female-sterility factors. There should not be any recombination between different loci which is the pivotal reason for the genetic degeneration of Y chromosomes. There are several theories attached to Y chromosome degeneration that are reviewed recently . Introduction: why are plant sex chromosomes

When Rashmi finally got an opportunity to speak‚ instead of focussing on the topic‚ she vented her anger by accusing the other candidate for being a male chauvinist and went on to defend women in general. What Rashmi essentially

Chemistry 121 Experiment 19 Molar Mass Determination y Depression of the Freezing Point Introduction: The most commonly used liquid is water. In this experiment we study the equilibria that can exist between pure water and an aqueous solution‚ and ice‚ the solid form of water. The heat will transfer from a higher temperature to a lower temperature. In order for water to change states of matter‚ it takes a certain amount of kinetic energy or heat. The shift from ice to water (solid to a liquid)

According to the Oxford English Dictionary‚ self-determination is the right or ability of a country or a person to manage their own affairs. Even though there are more than 208 nation states‚ there are still a number of people struggling for their rights towards self-determination. The United Nations Universal Declaration of Human Rights clearly states in Article 15 that everyone has the right to a nationality and no one shall be arbitrarily deprived of his nationality or denied the right to change

The expected heterozygosity (He)‚ in average‚ was higher than the mean observed heterozygosity (Ho) for ‘Big Sister’ populations‚ and Ho higher than He for ‘Enfant Terrible’ (Table 3). Departure from Hardy–Weinberg Equilibrium were significant at a 5% level (P<0.001) for only 3 populations (BANA‚ CAMP and ITAR). Based on the estimates of the inbreeding coefficient over all loci‚ the significant deviations were due to an excess of heterozygotes (negative GIS = more observed

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

Hardy-Weinberg Equilibrium One of the most difficult concepts to understand about the process of evolution is how changes in the genetic composition of a population affect the phenotypic composition of a population‚ and how both ultimately act to allow evolution of the species. Charles Darwin’s theory of evolution emphasizes that populations‚ not individuals‚ evolve. The purpose of my experiment was to test the allele and genotype frequencies. Alleles for a gene are represented by letters of
