Question: review part a nondisjuction is a cell division error in...

Question details

Review Part A Nondisjuction is a cell division error in which either homologous chromosomes or sister chromatids fail to separate and thus do not migrate to opposite poles. It is responsible for conditions such as monosomy (one member of a chromosome pair is missing) and trisomy (three copies of a chromosome is present rather than two) Jill is heterozygous for gene A and is going to have a child with Jack, who is homozygous recessive for gene A. Which of the following offspring genotypes could result from fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis ? Hint: It may be helpful to sketch the outcome of nondisjunction to solve this problem Select all that apply. Nondisjunction can occur during the first or second meiotic division. When nondisjunction occurs in meiosis I, homologous chromosomes fail to separate. When nondisjunction occurs in meiosis ll, sister chromatids fail to separate View Available Hint(s) AAa Aaa Aa 82 SubmitPart B Which of the following offspring genotypes could result from fertilization of a normal haploid sperm with an oocyte that had undergone nondisjunction in meiosis II? (Because a nondisjunction event in meiosis Il could involve the chromosome containing gene A or the chromosome containing gene a, be sure to consider both possibilities in your final answer Select all that apply. View Available Hint(s) AAa Aaa Aa SubmitPart C If Jack and Jill have a child with an Aaa genotype, during which meiotic division, and in which parent, could nondisjunction have occurred? Select all that apply. Meiosis l in the mother Meiosis I in the mother Meiosis I in the father Meiosis II in the father Submit Request Answer Part D If Jack and Jill have a child with an AAa genotype, during which meiotic division, and in which parent, could nondisjunction have occurred? Select all that apply. Meiosis l in the mother Meiosis Il in the mother Meiosis I in the father Meiosis II in the fatherPart E If Jack and Jill have a child with an aaa genotype, during which meiotic division, and in which parent, could nondisjunction have occurred? Select all that apply. Meiosis I in the mother Meiosis Il in the mother Meiosis l in the father Meiosis II in the father Submit Request Answer
