Gregor Mendel wondered is his principle of segregation worked with individuals who differed in two traits. To test this‚ Mendel crossed pure lined round‚ yellow seeds with pure lined wrinkled‚ green seeds. He predicted that the F_1 offspring would be heterozygous for both genes. Experiments had established that the allele for yellow seeds were the dominant allele (Y) and green seeds were the recessive allele (y). There were two different ways as to how seed shape and seed color would be passed onto

Running Head: ALBINISM ALBINISM Ivy Tech ANP 101 July 9‚ 2008 What is Albinism? Albinism is a hereditary disorder‚ which results in little or no production of the pigment melanin. The disorder is not an infectious disease and cannot be transmitted through contact‚ blood transfusions‚ or other means. Albinism is usually‚ but not always‚ apparent in a person’s skin‚ hair and eyes. The most recognizable form (called oculocutaneous albinism or OCA)‚ results

Genetics With Drosophila Flies Josh Derrall Lab Group: Dana Gilkes James Lupo Olivia Giannola December 4‚ 2012 Prof. Hunter Introduction Genetics is a topic that has been studied for hundreds of years. One of the most notable geneticists was Gregor Mendel. Mendel studied basic inheritance patterns and gene expression using pea plants. Mendel determined that the offspring of two parents contains one gene from each parent (McKusick 1983). However‚ since Mendels discoveries

Report 1: Genetics-411 Population Genetics of Albinism in Zea mays Spring 2013 2/16/2013 Tory Thomason Introduction Zea mays or maize was chosen as the study system for this experiment for many reasons. The phenotype being studied is observable to the naked eye‚ green or yellow plants. It is an important agricultural system used in crop and is an ideal genetic model. Zea mays also has a quick turnaround time from generation to generation and crossing Zea mays

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

Part I 1. Contrast the terms mutation and polymorphism. Mutations are “substitution patterns during gene divergence across vertebrate species” (Lourenco‚ Galtier & glemin‚ 2011‚ p. 67). In the case of species divergence “changes in population sizes or environmental changes can move populations away from equilibrium” (Lourenco‚ Galtier & glemin‚ 2011‚ p. 67). On the other hand‚ polymorphism is when “diverted natural selection rooted in differential resource…can generate and maintain

Gregor Mendel believed that genes followed “natural laws” and could be expressed in simple mathematical terms (Brooker 19). He was mostly intrigued by how genes varied as they pass from generation to generation (Brooker 18). Mendel decided to test his mathematical hypothesis using pea plants since they came “in several varieties‚ which varied in height and in the appearance of their flowers‚ seeds‚ and pods‚” (Brooker 19). He also decided to use self-fertilization and cross-fertilization to see which
