different alleles. Alleles are the specific characteristics of the gene. These alleles can be dominant or recessive. A dominant allele has a different phenotype than a recessive allele. Phenotypes are simply the observable traits seen in a living organism. An example of phenotype is a dominant allele for hair color is Brown‚ while the recessive allele for hair color is Blonde. They both are for the same gene‚ but are different outcomes of the gene. A dominant allele overrides a recessive allele. In order

Introduction Allozyme analysis is a technique which is used in study of genetics because it reveals the genetic variation that exists within a wide range of organisms (Gómez‚ 1998). Allozymes are different forms of an enzyme expressed by alternative alleles on the same gene locus (Micales & Bonde‚ 1995). Analysis of these allozymes can be done by protein electrophoresis. Protein electrophoresis involves the movement of proteins within an electric field with mobility being dependent on factors such as

submit this assignment to your teacher by the due date for full credit. Part 1: Monohybrid Cross—Predicting Freckles in an F1 Generation Apply your understanding of how alleles assort and combine during reproduction to evaluate a scenario involving a monohybrid cross. The allele for having freckles (F) is dominant over the allele for not having freckles (f). Some characteristics in people are inherited as simple dominant and recessive traits. One example is freckles. Freckles is a dominant trait

fingerprints meaning that no two tigers have the same pattern of stripes. White tigers aren’t necessarily born from other white tigers. White tigers get their color by a double recessive allele. A Bengal tiger with two normal alleles or one normal and one white allele is colored orange. Only a double dose of the mutant allele results in white tigers (www.cranes.org/whitetiger). In fact it is even normal to find normal colored cubs in a litter of white tigers (www.5tigers.org.com). White tigers are a very

Know definitions of the words used for Meiosis‚ Mendel’s work and Genetics Dominant – expression that is always expressed when its gene recessive - An expression that is expressed only when its allele is the only form of the gene present in the genotype. incomplete dominance - Neither allele is dominant to the other‚ thus each is expressed in the heterozygous genotype producing an intermediate phenotype. EX. Red (RR) and White (R’R’) snapdragons produce pink (RR’). epistasis - A condition
