Genetics of Drosophila First‚ Drosophila is the common fruit fly. The common fruit fly is some of the best organisms to study for genetic research and experimentation. This is true for a few reasons‚ the first of which is the small number of chromosomes which is 4‚ and that we have identified the genome. This means all traits are known and we can figure out where mutations take place. The second reason is the fly’s ability to reproduce quickly. A new generation is produced every week‚ allowing

Genetics Experimental Analysis Set #2 Linkage 1. In gorgonzolas‚ there are three recessive traits that affect the organism’s appeal: shrunken fruit‚ foul-smelling flowers‚ and short height. A heterozygote was crossed with a homozygote‚ yielding the following offspring: 46 - foul-smelling 44 - shrunken fruit‚ short height 8 - short height 8 - shrunken fruit 7 - foul-smelling‚ short height 6 - foul-smelling‚ shrunken fruit 3 - foul-smelling‚ shrunken fruit‚ short

Genetic engineering is a powerful and potentially very dangerous tool. To alter the sequence of nucleotides of the DNA that code for the structure of a complex living organism‚ can have extremely ill effects although the potential benefits can be huge. Before advances in genetic applications‚ gene therapy was unheard of and genetic defects were always inherited‚ plaguing generations. Today genetic testing is widely available‚ such as prenatal karyotyping of chromosomes to check for genetic abnormalities

ourselves with as much information as possible? Is homosexuality genetic‚ or does it start in the home? Although I did not find conclusive evidence to support genetics or nurture as the cause of homosexuality‚ I do feel there is enough logical theory to dismiss the “Gay Gene” as the cause of homosexual behavior. Research on this subject was hard to find‚ but I was able to gather some of the most popularly used material on homosexual genetics. I have analyzed all the information I have gather‚ looking

Factors affecting pre-natal development a. Maternal Health Since the placenta cannot filter out extremely small disease carriers‚ such as viruses‚ children can be born with malaria‚ measles‚ chicken pox‚ mumps‚ syphilis‚ or other venereal diseases that have been transmitted from the mother. Rubella is the most widespread of the viruses that have a teratogenic effect. If a pregnant woman contracts rubella in the first three months of pregnancy‚ she is likely to give birth to a child with

ABSTRACT The microevolution of Alu element TPA-25 was tested in the experiment through the examination‚ observation‚ and analysis of population alleles distribution under the Hardy-Weinberg Theory of Genetic Equilibrium. Alu elements affect the genome by causing insertion mutations‚ recombination between elements‚ gene conversion‚ and alterations in gene expression. In the lab PCR was used to amplify a short piece of DNA from human genome which allowed us to look for a DNA sequence called an Alu

bioengineering have helped us develop a better understanding of the origins from which humans and other living creatures spur. The discovery of the Deoxyribonucleic acid (DNA) is the key to all bioengineering. The DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. An allele is one of two or more forms of the DNA sequence of a particular

that run through a mother-to-be’s head. In the midst of all the excitement that comes with planning for a new baby‚ parents tend to forget how important maternal health is for prenatal development; The three factors or hazards I feel that are the most important for parents to understand or remember during and for prenatal development are alcohol consumption‚ smoking and second-hand smoke inhalation‚ and chemical and drug intake. Alcohol is a vice of many. According to the National Institute on
