Inversion Problems: An individual is heterozygous for an inversion: ADCBEFG HI, and during gamete formation there is a crossing over event between C and B. Draw chromosome structure pre and post meiosis. Be sure to label the chromatids/chromosomes with the appropriate sequence of genes. Label mutant and wild type chromatids/chromosomes, viable and non-viable gametes. Circle and identify the mutations in the non-viable gametes inuerston If an individual is heterozygous for an inversion, ABC DGFEHI, and a crossing over event occurred...

Down syndrome, or trisomy 21, in humans is caused by an extra copy of the relatively small, acrocentric 21. Including only chromosome 21, the X chromosome (medium in size and somewhat metacentric) and the Y chromosome (small and acrocentric), draw one possible array of chromosomes in the four sperm cells produced by the complete meiosis of one primary spermatocyte in a male individual with Down syndrome. For the purposes of this question, assume that males with Down syndrome produce normal...

2. (5 PTS) You are presented with a patient, named Gerry, who has Down syndrome (trisomy 21). You determine that the nondisjunction event occurred in his mother, named Mary, during meiosis I. a. You are interested in the TPTE gene, which is near the centromere of chromosome 21. Virtually no recombination occurs between the centromere and the TPTE gene. Mary has two different alleles of the TPTE gene. Would Gerry's two chromosome 21s from his mother have the same or...

22. [9 PTS] Turner syndrome results when an individual has a genotype of XO (a single X chromosome), and no other sex chromosomes. Color-blindness results from mutation of a single gene on the X chromosome. A couple, both of whom have normal color vision, have a color-blind child with Turner's syndrome. a. Did non-disjunction occur in the mother, or the father, or is it impossible to tell? Explain your answer. (3 pts) (continued next page. b. In the space provided...

Question 25 Not yet answered Points out of 2.50 Klinefelter syndrome XXY is the set of symptoms that result from two or more X chromosomes in males. The primary features are infertility and small poorly functioning testicles. However, very often, symptoms may be subtle and many people do not realize they are affected. Which of the following statements might explain why symptoms are subtle in many Flag question cases? Select one: a. In males, the important sex chromosome is the...

Practice Using a Punnett Square. Punnett Squares are tools to identify outcomes known genotypes. They can be used to help infer probabilities of genotypes and from a particular cross. of possible crosses between individuals of phenotypes amongst offspring lele forms "A" and "a".

Nameindulia Los Drosophila Genetics Predictions-L113 (20 pts.) Part I. Meiosis and Punnett Squares Remember, whenever you use Punnett Squares to solve genetics problems, be sure you are completing each of the following steps: 1) Identify the genotypes of the parents. 2) For the specific traits of interest, figure out what kinds of haploid gametes each parent can make. In each gamete, there should be one allele for each trait of interest. If there is more than one trait, make sure...
