Genetics of Organisms Nicole Ryan AP Biology 2/2/15 Block 1 Introduction and Background Drosophila melanogaster or more commonly referred to as “fruit flies” have been used for genetic research for over 100 years. During his time at Harvard university‚ Charles W. Woodworth is credited with being the first to suggest fruit flies be used for genetic research. A century later‚ fruit flies are the most widely used eukaryotic organism for genetic research (Drosophila)

homozygous recessive for that trait so the unknown genotype can be determined from the offspring. • Law of independent assortment o Law of segregation involves 1 character. What about 2 or more characters…? o Monohybrid cross (hybridization using a single trait with two alleles) vs. Dihybrid cross (hybridization using two traits with two alleles each) o The two pairs of alleles segregate independently of each other. • Non-single gene genetics o Incomplete dominance: appearance between

Kyle Eagle Human Biology BIO 108 G Final Exam Essays FINAL EXAM ESSAY 1). A cell is in the process of transcription. The single strand of DNA that is being copied has the sequence ATC GCA GGA TGC. Indicate the mRNA strand that will be synthesized from this strand‚ listing the correct sequence of bases. Describe why this step is important in the process of producing proteins. Explain how gene expression is regulated. The mRNA coding sequence can be described as units of three nucleotides

Chapter 10 Foundations of Genetics Lecture Notes 1 Foundations of Genetics Mendel and the Garden pea The father of modern Genetics is Gregor Mendel. Gregor Mendel (1822-1884) was an Austrian monk who lived in a monastery where the experiments with the garden pea were performed. Mendel’s work with the garden pea was the fundamental study which unveiled the laws that govern genetics and heredity. Mendel was the first to use the scientific method in a very systematic and analysed his results

Gregor Mendel and the Principles of Inheritance Intro: In the 1800’s‚ a hypothesis existed that suggested that genetic material is contributed by the two parents by mixing an equivalent way. However‚ this “blending hypothesis” did not last long due to the discovery that if this had been true‚ we would end up with a uniform population of individuals. Gregor Mendel‚ a scientist and monk‚ documented a particulate mechanism for inheritance. This was developed before chromosomes were observed under

produce about three-fourths white and one-fourth yellow offspring. What are the genotypes of these two parents? What will each produce if crossed with a yellow-fruited plant? Note that a phenotypic ratio of 3/4 to 1/4 is what you expect from a monohybrid cross between two heterozygous parents (Ww x Ww). Note that the second cross (to a yellow-fruited plant) is a testcross (a cross beetween an individual with the dominant phenotype and a homozygous recessive parent). The progeny expected from such

tests‚ Morgan and his colleagues discovered the Chromosomal Theory of Inheritance. In addition‚ for genetic crosses of fruit flies‚ there are three types of inheritance patterns that are relevant in this lab. The first is monohybrid - one single trait is involved‚ the second is dihybrid - two different traits are involved‚ and sex-linked - the pattern of inheritance that results from a mutant gene located on either the X or Y chromosome. Also‚ in relation to genetic crosses‚ it is necessary for the females
