    those people because they have alleles for “lefty” and “righty”‚ but only one is normally shown‚ but if you work at it‚ both could be used. For example‚ in the sport of Lacrosse‚ most of the better players’ stick skills are equal on their left hand and right hand. Therefore‚ no gene for handedness should be dominant over the other. After doing some research‚ I have come to the conclusion my theories were incorrect and that handedness has a dominant and recessive allele. According to psychologistworld

    Discussion The goal of the experiment was to determine what gene or genes are responsible for the white eye phenotype of two strains of Drosophila melanogaster. According the literature‚ the w+ gene is located on the X chromosome at 1.5 genetic map units (1). In addition‚ the st+ and bw+ genes are autosomal and assort independently‚ meaning they are two different genes located on two different chromosomes. It is stated that the bw+ gene is located on the 2R chromosome at 104.5 map units (2)

    Simulate Mendel’s experiments using a dihybrid cross‚ in which he defined the law of independent assortment. Use two physical traits in dragons – Color and body covering. The color locus has two alleles: Green (G) which is dominant‚ and yellow (g) which is recessive. The skin locus also has two alleles: Scaled (S) is dominant to scaleless (s). a. What types of dragons would you use as the parental generation? b. What would be the phenotype(s) of the F1 generation dragons? c. Write out the

    W4Q1 Meiosis is the process by which cells divide and create living creatures. Without meiosis we cannot have the process of mitosis‚ which is the process by which cells of tissue are created for living creatures. When meiosis occurs 4 daughter cells are created‚ while only 2 are created in mitosis. With the creation of 2 daughter cells the new cells will be similar to the parent cell‚ but will have differences‚ as there more parent cells involved. When mitosis occurs the daughter cells will be

    controlled by a dominant factor. Chromosomes are threadlike structures made up of DNA and protein‚ while a gene is a segment of DNA on a chromosome that controls a particular trait. An allele is an alternate form of a trait. Homozygous means that all of the alleles are the same in the DNA‚ and heterozygous means that the alleles are mixed up. For example‚ homozygous would be PP or pp‚ and heterozygous would be Pp. The dominant factor is uppercase‚ and the recessive trait is lowercase. Gregor Mendel’s legacy

    A Roman Catholic monk‚ Gregor Mendel (1822-1884)‚ was raised on a farm and enjoyed gardening and mathematics. In 1856 he started to experiment with pea plants to explain why certain traits that appeared in one generation did not always reappear in the next generation. During eight years Mendel mixed over 30‚000 plants by controlling their pollination and wanted to know why the results came to be. Mendel noticed that although there were some traits that were common amongst all the pea plants there

    Scientific Paper 4-10-13 Determining the Unknown Genotype of Corn Plants of the Zea mays Species from the Phenotypes of Offspring Produced Abstract No one particular organism is an exact replica of another. Diversity in the world is key for future generations to adapt to the fast changing world. This lab observed the corn plant of the Zea mays species to determine the genotype for the gene of tall versus dwarf in unknown parent corn plants by observing the seedlings produced. It was hypothesized

    Introduction Drosophila melanogaster is a common fruit fly that has been useful for most experiments in the study of Genetics. The male and the female fruit fly are similar and different in regards to how they look‚ structurally. They are similar because both genders have a head‚ thorax‚ proboscis‚ antennae‚ eyes‚ and mouth parts. However‚ males are smaller than females and have about five abdominal segments as opposed to the seven that the female has. The life cycle of these fruit flies consist
