2. Carefully analyze the following images. C (1 or 2 "sets" of information is held on how many chromosomes). Also indicate how much DNA is in each compared to a respective gamete which has 1x amount of DNA) a. Describe each as n= Ploidy (2n or 1n?) 1n_ # of chromosomes _2_ amount of DNA _1x_

Instructions: Fill in the appropriate definition in your own words (do not just copy from slides). Structural Chromosomal Mutations: *These are different b/c they effect the entire chromosome! 1. Deletion: 2. Inversion: 3. Translocation: 4.. Duplication:

The Karyotype • Karyotype [KAER-ee-oh-tihp]: To prepare a karyotype: A cell sample is collected and treated to stop The sample is stained, which produces chromosomes that is clearly visible under a microscope Chromosomes are and The autosomes are numbered, labelled as K » X }( 13 . 19 ❤. 15 20 {{ 10 16 21 on the and the sex chromosomes are 25 12 K= during 22 12 18 Su X/Y

18. This question refers to the following schematic diagram of two normal chromosomes and five aberrant forms (A through E) of those chromosomes. (Circles represent centromeres and letters represent genetic loci). Which of the aberrant forms represents duplication? Normal Chromosomes (A) (B) | (D) (E)

39 The structures labelled A and B in the image below represent: СТАААТСGGT. Allele for red flowers B Enzyme A Allele for white flowers One allele sufficient to ATAAATCGGT produce half the pigment Select one alternative: O the locus for flower colour; a red flower the locus for flower colour; a white flower O non-homologous chromosomes; a red flower O homologous chromosomes; a pink flower

2. An organism is 2n=4 with genotype AaBbEe. Genes A and B are close together on the larger chromosome, and gene E is on the smaller chromosome. a. Using a vertical metaphase plate, draw the two independent orientations of this AaBbEe cell in Metaphase I of Meiosis. b. Label alleles on all chromatids. c. Write the alleles in each possible gamete on the lines below each orientation. OR O'Q ( Gametes:
