MENDEL`S PRINCIPLES OF GENETICS 1.0 INTRODUCTION: 1.1 BACKGROUND Gregor Mendel‚ who is now considered as founder of classical genetics‚ ( Elrod S. & Stansfield w‚2010)‚ conducted a series of experiments using garden pea plants‚ his aim was to find a way of explaining to his fellow scientists who believed the blending theory which had been proposed earlier by Wiseman‚ that heredity involved the interaction of discrete separable factors (now known as genes) After a statistical analysis of the

base is attached to carbon 1 of the sugar‚ biologist denote each of the carbons in the sugar using a number from 1 through 5‚ where 1 represents the carbon to which the base is attached. 2. How does an organism’s genotype determine its phenotype? The genotype of an organism is the sum total of all the genes that it inherits. It is sort of like a blue print that is designed to serve as a guide in the development of the organism‚ so that it will become the same kind of creature as the

E) a breeding experiment in which the parental varieties have only one prominent trait. 2) Which of the following statements regarding genotypes and phenotypes is false? A) The genetic makeup of an organism constitutes its genotype. B) An organism with two different alleles for a single trait is said to be heterozygous for that trait. C) Alleles are alternate forms of a gene. D) An allele that is fully expressed is referred

Simulated ABO and Rh Blood Typing Background information: Science Kit and Boreal Laboratories Protocol (Materials and Methods): NeoSci ABO-Rh Typing Using Neo/BLOOD Introduction Around 1900‚ Karl Landsteiner discovered that there are at least four different kinds of human blood based on the presences or absence of specific agglutinogens (agglutinating antigens) on the surface of red blood cells (RBCs‚ also known as erythrocytes). These antigens have been designated as A and B. Antibodies

After much thought and consideration‚ I have come to the difficult conclusion that having an abortion would be the most humane decision‚ not only for the baby‚ but for myself (the mother) and for my theoretical spouse‚ children‚ and other family members. Trisomy 13 is an awful chromosomal abnormality that has no cure. This is not a disease such as down syndrome that a child could live with. Research has shown that most babies with Trisomy 13 do not even live to be a year old. The rare percentage

A person’s genotypes is their genes‚ which make up their DNA. Alleles are the types of genes‚ come in pairs in a gene‚ and are responsible for a person’s phenotypes(Wanjie 29). Phenotypes are the physical characteristics of a person. Alleles are either characterized
