Short Answer 3. The pedigree shown is of a family with an X-linked recessive disease. The sex chromosomes are indicated. Individual Il-2 is the result of a non-disjunction event in one of the parents. A) If the nondisjunction event that gave rise to Il-2 occurred in the father, in which phase of meiosis did it happen? Explain your reasoning. X"X XY 1 XXY

3 (Lecture 13 Study Guide, Question #10) Genetic traits on the X-chromosome are called X-linked. Some X-linked conditions are referred to as X-linked dominant, such as Fragile X Syndrome. Consider the following genetic cross: A father with Fragile X Syndrome and a mother with normal phenotype. Perform a Punnett Square. Select the possible genotypes of their offspring below. xFxf xFY

Short Answer 4. You identify two recessive mutations in fruit flies, one that results in curly wings (cc) and one in an ebony body (ee). You cross two flies that are heterozygous for both traits (CcEe), and find 352 flies progeny in the next generation with the following phenotypes: wild type - 193 wild type wings, ebony body - 69 You believe the curly and ebony alleles assort independently and are not linked. Perform a chi square analysis for this cross to test the null hypothesis. A) Show at least the following parts of your work: the expected vs. observed numbers for each phenotype, and the final X² value. Observed Expected (o-e)²/e wild type body, curly wings - 64 curly wings, ebony body - 26 Edit View Insert Format Tools 12pt ✓ Paragraph Table X² U AV T² v BIUA V V QV G✓ ⠀
