Fast Plants Lab Background Gregor Mendel is an Australian monk‚ who worked in a garden at a monastery. He experimented with pea plants‚ and soon became known as the father of genetics. The reason he studied pea plants was because they grow quickly‚ the traits can be easily observed‚ and the plant is easy to pollinate. Mendel’s method was to control the pollination of the pea plants and create offspring’s of the two plants that were pollinated together. Using self-pollination and cross pollination

Exam 1: The complete set of hereditary information carried by an organism is its genome Human DNA contains 20% C on a molar basis. What are the mole percents of A‚ G‚ and T? A- 30% G- 20% T- 30% In a polynucleotide‚ a phosphate group is linked to the 3’ and 5’ carbons 2 pentoses Which of the following is a transition mutation? A-T —> G-C - transition= purine —> purine or pyrimidine —> pyrimidine - Purines- GA - Pyrimidines- CT The basic building block of nucleic acids is the nucleotide

Chapter 13 SQ3Rs 13.1 Questions: 1) What are applied genetics? 2) How is selective breeding useful? 3) Explain the process of hybridization. 4) What are the dangers of inbreeding? 5) When doing a test cross‚ what are some things you must do? Answers: 1) Applied genetics is using genetics to as a technology to further advance and improve life. 2) Selective breeding is used to get desired traits to later generations. 3) In the process of hybridization‚ which is a form of

INTRODUCTION TO DROSOPHILA GENETICS DROSOPHILA CULTURE We will study basic principles of Mendelian inheritance with the use of the fruit fly‚ Drosophila melanogaster [the name means “black-bodied fruit-lover”]. Drosophila was one of the first organisms to be studied genetically: its small size‚ short life cycle (10 ~14 days at 25oC)‚ high reproductive rate (an adult female can lay 400-500 eggs in 10 days)‚ and ease of culture and genetic manipulation have made it perhaps the best understood animal

Fruit Fly Lab Introduction The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance‚ where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this lab was formulated by a man often times called the "father of genetics‚" Gregor Mendel. He determined that individuals have two alternate forms

Assignment #2 – Patterns of Inheritance First: Answer the following question. Which disease types‚ autosomal dominant or autosomal recessive are generally more common / persistent in populations? Explain your answer. (Please do not guess or otherwise invent your answer! Rather‚ do some research and reading‚ i.e. Chap. 14!) Sickle cell disease is a autosomal recessive trait that occurs due to the single base substitution in DNA. Second: Demonstrate this principle by showing the population

If a red flowering plant mates with a pink flowering plant‚ what phenotypes are possible in their offspring? Show the phenotypic ratio also. 2 In humans‚ freckles are dominant to no freckles. If a male with no freckles mates with a female who is heterozygous for freckles‚ what is the probability of their child having freckles? 3 Cystic fibrosis is transmitted
