    Chapter 13: Meiosis and Sexual Life Cycles 1) Genes are the units of heredity‚ and are made up of segments of DNA. 2) In asexual reproduction‚ one parent produces genetically identical offspring my mitosis. In sexual reproduction‚ two parents give rise to offspring that have unique combinations of genes inherited from the two parents. 3) Humans have somatic cells‚ which are any cell other than a gamete‚ have 23 pairs of chromosomes. A karyotype is an ordered display of the paired of chromosomes

    Review Questions & Answers (1/23) 1. Explain the difference between haploid and diploid cells. Tell where in an organism they are found. Tell how they are produced. A haploid cell is a cell that contains one complete set of chromosomes. Gametes(sperm and ova) are haploid cells that are produced by meiosis. Diploid cells contain two complete sets (2n) of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas. Some examples are skin‚ blood‚ muscle cells

    flower color‚ is regulated by a pair of genes called alleles. These alleles are found at particular places on the chromosomes called loci. During meiosis‚ each pair of alleles splits up or segregates so that only one allele from each pair is contained within a gamete (egg or sperm.) This is Mendel’s Law of Segregation. In sexual reproduction egg and sperm from parents unite to form a new individual or zygote. Thus‚ each parent contributes one allele for each genetic locus. Mendel’s Law of Independent

    chromosome linked dominant or recessive‚ Y- chromosome linked or not. Explanation 1. Autosome Linked Dominant traits: These are the traits whose encoding gene is present on any one of the autosomes‚ and the wildtype allele is recessive to its mutant allele‚ i.e.‚ the mutant allele is dominant. The pedigree-chart can be of the undernoted pattern (Fig. 11.2)‚ where the female being interviewed is exhibiting the trait‚ and is indicated by an arrow-mark in the chart. The characteristic features

  • Mendelian Inheritance in Drosophila

    discovered by Gregor Mendel in both the monohybrid and dihybrid cross. The ability to test these ratios stems from the use of Mendel’s law of segregation which states that during meiosis allele pairs will separate in gametes so one of each allele is present in a gamete. (Garey‚ et al‚pg 8-13) These single alleles are then combined with the other parental gamete forming a new somatic cell. Another important law is the law of independent assortment which means that different gene pairs will separate

  • Genetics Jargon - a Mini Dictionary

    GENETICS JARGON Alleles (allelomorphs) Alternative forms of a particular gene. There can be several alleles of a particular gene in the population‚ but only 2 alleles can be inherited by a single individual. For simplicity much literature aimed at the general reader uses "gene" where it means "allele". Allelic Series A series of alleles that are all mutant forms of the same gene and are at the same locus (same position on the chromsome). Alternate Heredity Mendelian inheritance involving

    TESTING OF ALLELE DOMINACE IN GENES WHEN TASTING PHENYLTHIOCARBAMIDE (BASED ON MEDELLIAN GENETICS) ABSTRACT; The hypothesis is that we will gain a 3:1 ratio‚ where the tasters show to have the dominant allele. We do not expect to see a difference between the observed and the expected data; therefore stating our hypothesis was supported‚ meaning the most dominant and outstanding allele is the one that allows people to the phenylthiocarbmide (PTC). Our hypothesis was supported. INTRODUCTION;

  • Biol 2104 Lab Report 2 Electrophoresis

    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
