People with Down syndrome have an extra copy of chromosome 21, for a total of 47 chromosomes. However, in a few cases of Down syndrome, 46 chromosomes are present. This total includes two normal-looking chromosomes 21, one normal chromosome 14, and a longer-than-normal chromosome 14. Interpret this observation. How can these individuals have 46 chromosomes?
In humans, each cell normally contains a diploid (2n) chromosome number of 46. Say that a human body cell and sex cell will undergo mitosis and meiosis respectively, provide the number of chromosomes in each cell for every stage. Stage of Mitosis Number of Stages of Meiosis Number of Chromosomes in Chromosomes in One Cell One Cell Prophase 2n = Prophase 1 2n = Prometaphase 2n = Prometaphase 1 2n = Metaphase 2n = Metaphase 1 2n = Anaphase 2n = Anaphase 1 2n = Telophase and Cytokinesis Telophase 1 and Cytokinesis 2n = n = Prophase 2 Prometaphase 2 n = Metaphase 2 n = Anaphase 2 = u Telophase 2 and Cytokinesis n =
Human somatic cells have 46 chromosomes. How many chromosomes are present in human cells undergoing each of the following phases of meiosis? Interphase - Answer: 0 2 3 4 6 9 2 Prophase I - Answer: 0 2 3 4 6 9 2 Prophase II - Answer: 0 2 3 4 6 9 2 Telophase I - Answer: 0 2 3 4 6 9 2 Telophase II - Answer: 0 2 3 4 6 9 2
A diploid cell has 15 picograms of DNA in G₁ phase. If this cell is a germ line cell that undergoes meiosis, how much DNA will each daughter cell contain at the end of meiosis I? How much DNA will each daughter cell contain at the end of meiosis II? MI = 30 pg: MII = 15 pg O MI = 15 pg; MII = 15 pg MI = 7.5 pg; MII = 15 pg O MI = 15 pg: MII = 7.5 pg
A somatic cell has the genotype DdEe. All chromosomes in this organism are metacentric. Show metaphase and the results of mitosis if the D and E locus are linked on the same chromosome in trans configuration. A sexually reproducing organism has the following phenotype DdEeAaTt: The D and E loci are on the same arm of a metacentric chromosome in cis configuration. The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. 2.1. What is the haploid number of this organism? 2.2. Using diagrams show a ceii at metaphase of mitosis and show the results of mitosis.
Suppose there are two genes on two different chromosomes, one gene called G and the other called D. An individual has the genotype GgDd. Which of the following drawings correctly shows cells in this individual after DNA replication but before cell division of the first meiosis? Assume no recombination/crossing-over occurs between the chromosomes. a) G|GgTg 11 11 D--Da-d 1 N Gg Gg D-d Dd b) d) G+gGg 7/2007 D-d D-d GG gtg DD dd
Diploid somatic cells of elephants have 56 chromosomes. If nondisjunction of one of a male elephant’s chromosomes occurs in meiosis II, at the end of meiosis the four resulting sperm are expected to have the chromosome complement:
Match the following: A duplicated chromosome is made of 2.A maternal and paternal chromosome present together, each with two sister chromatids 3.Semi-condensed DNA made up of coiled nucleosomes. 4.Super-coiled DNA strands. 5.Contains only one copy of each chromosome. 6.Name of an error during meiosis resulting in fewer chromosomes than normal in a zygote or individual (2n-1) 7.General term for an error resulting in the incorrect number of chromosomes in a gamete after meiosis 8.A specific version of a gene, such as blue eye colour 9.A region on a chromosome that codes for a protein 10.Region where chromosomes are attached 11.None of the above (should be selected more than once) with monosomy trisomy aneuploidy centromere gene sister chromatids diploid Haploid tetrad telomere Chromosomes Chromatin allele
Human somatic cells have 46 chromosomes. Are the cells different in any way from the parent cell and what is chromosome count of each of those cells once they have finished mitosis?
In a turtle species, a diploid cell in the G1 phase of the cell cycle contains 22 picograms of DNA (picogram is a measure of the total mass of the DNA present). How much DNA is present in a cell of the same species at prophase II of meiosis (prophase of the second meiotic division)?
A prairie grass species called "little bluestem" is tetraploid. It has four complete sets of chromosomes. There are ten kinds of chromosomes; in other words, each complete set of chromosomes has a total of 10 chromosomes. A single somatic cell (e.g., a cell in a leaf) will have 40 chromosomes, 4 of each kind of chromsome, i.e., 4 of the number 1 chromsome, 4 of the number 2 chromsome, etc. The illustration below shows prophase of meiosis 1 in chromosome number 10. In a diploid cell, there would be one tetrad (group of 4 chromatids) for each kind of chromosome. For example, there would be one tetrad for chromosome 8, one for chromsome 9, etc. When the tetraploid little bluestem undergoes meiosis, how many of chromosome number 10 will each sperm cell carry?
An individual is heterozygous for a reciprocal translocation, with the following chromosomes: A • B C D E F A • B C V W X R ST • U D E F R ST • U V W X Q. Draw a picture of these chromosomes pairing in prophase I of meiosis.
