(Cell Cycle stages are Interpahse, Mitosis and Cytokinesis) Slide 4 The phase in Interphase during which the cell prepares for division and the centrioles replicate Slide 5 What is Growth 2 or Gap 2 (G2)? Interphase has three stages: G1 Rapid growth and metabolism S DNA synthesis and replication G2 Preparation for division and centriole replication Slide 6 During this stage, (1) spindle fibres break down and disappear, (2) a nuclear membrane form around each of the two new sets of chromosomes and (3) the cytoplasm divides between the two halves of the cell Slide 7 What is Cytokinesis? Slide 8 It consists of two sister chromatids held together by a centromere Slide 9 What is Chromosome? Slide 10 They are identical genetic copies of each other Slide 11 What are Sister Chromatids? Slide 12 Increase the number of cells, regenerate damage tissues, and replace dead cells Slide 13 What is the function of mitosis? Slide 14 Third phase of mitosis where the centromeres splits apart and the chromatids are pulled to the opposite poles of the cell by the spindle fibre Slide 15 What is Anaphase? Slide 16 The product of mitosis Slide 17 What is two genetically identical Daughter Cells? Slide 18 Caused by toxic substances, radiation or viruses, these changes become permanent error and become copied during Prophase Slide 19 What are Mutations? Slide 20 In plant cells, this must develop between the two newly forming cells in order for cell walls to properly separate Slide 21 What is a Cell Plate? Slide 22 The production of reproductive cells called gametes Slide 23 What is the function of Meiosis? Slide 24 Similar chromosomes that form pairs during Prophase I Slide 25 What are Homologous chromosomes? Slide 26 It occurs in Prophase I when non-sister chromatids wind around each other and exchange segments of chromosomes to create new genetic combinations in the gametes Slide 27 What is Crossing Over? Slide 28 Eight Slide 29 What is the number of phases in Meiosis? Slide 30 It is term defining the end result of meiosis (i.e., the production of gametes that are either egg or sperm) Slide 31 What is Gametogenesis? Slide 32 When this allele is present, it is the trait that will always be expressed (i.e., appears) Slide 33 What is Dominant? Slide 34 The offspring produced by cross of the two different purebred parents of the P Generation Slide 35 What is Filial Generation or F 1 Generation or Hybrid? Slide 36 It is the law that states that inherited traits are determined by pairs of factors AND the factors separate so that there is one factor in each gamete Slide 37 What is the Law of Segregation? Slide 38 The Mendelian Ratio in the F 2 Generation that occurs in a monohybrid cross Slide 39 What is 3:1? (Dominant Trait is expressed 75% of the time and the Recessive Trait occurs 25% of the time) Slide 40 Term for an organism with one dominant allele and one recessive allele Slide 41 What is Heterozygous Dominant? Slide 42 PpRr Slide 43 What is a heterozygous dominant gentoype? Slide 44 It is the ratio of F 2 Generation offspring produced by crossing two hybrid F 1 Generation organisms (i.e., heterozygous dominant) Slide 45 What is 9:3:3:1? Slide 46 It is the only way the recessive traits can be expressed in the F 2 Generation of a dihybrid cross Slide 47 What is if all alleles in the genotype are recessive (e.g., pprr)? Slide 48 It is the law that states that the inheritance of alleles for one trait do not affect the inheritance of alleles for another trait Slide 49 What is the Law of Independent Assortment? Slide 50 Genetic cross between hybrids that differ in two traits Slide 51 What is a Dihybrid Cross?
