- Familial Down syndrome is similar to primary Down syndrome in that it is caused by trisomy 21. However, in familial Down syndrome, all or part of the third copy of chromosome 21 has translocated onto another autosome, typically chromosome 14. In cases of familial Down syndrome, one of the parents of the affected child is often a carrier of a translocated chromosome. The translocation carrier parent does not have Down syndrome because he or she has a total of two copies of chromosome 21. Suppose that a woman is a translocation carrier of chromosome 21 on chromosome 14. She conceives six zygotes with a man who carries no aneuploidies. Match the description of the chromosomes inherited by each zygote with the viability and phenotype of the zygote. ✓ Two normal copies of 14, two normal copies of 21 two normal copies of 21, one normal copy of 14 ✓one normal copy of 14, one 21 to 14 translocation, one normal copy of 21 ✓two normal copies of 14, one normal copy of 21, on 21 to 14…A phenotypically normal individual has the following combinations of normal and abnormal chromosomes:The normal chromosomes are shown on the left in each pair.Suggest a series of events (breaks, translocations, crossovers, etc.)that may have produced this combination of chromosomes.Neurofibromatosis 1 is considered an autosomal dominant disorder because the gene is located on the long arm of chromosome 17. It is caused by microdeletion at the long arm of chromosome 17 band 11 sub-band 2 involving the NF1 gene. Group of answer choices Statement 1 is correct. Statement 2 is incorrect Statement 1 is incorrect, statement 2 is correct Both statements are incorrect Both statements are correct
- Identify the type of chromosomal aberration described in each of the following cases and provide and example. loss of a chromosome segment extra copies of a chromosome segment reversal in the order of a chromosome segment movement of a chromosome segment to another, non homologous chromosomeFrom 2 to 6 percent of people with autism have an extra chromosome that consists of two long arms of chromosome 15. It includes two copies of the chromosome 15 centromere. Two normal copies of the chromosome are also present. What type of chromosome abnormality in a gamete can lead to this karyotype, which is called isodicentric 15?Referring to image of chromosome 16 below, indicate the exact location of the genes labeled a-k:
- A phenotypically abnormal individual has a phenotypically normalfather with an inversion on one copy of chromosome 7 and a phenotypicallynormal mother without any changes in chromosomestructure. The orders of genes along the two copies of chromosome7 in the father are as follows: R T D M centromere P U X Z C (normal chromosome 7)R T D U P centromere M X Z C (inverted chromosome 7) The phenotypically abnormal offspring has a chromosome 7 withthe following order of genes: R T D M centromere P U D T R Using a sketch, explain how this chromosome was formed. In youranswer, explain where the crossover occurred (i.e., between whichtwo genes).Complete the table: Chromosomal Abnormalities Name of Abnormality Number of autosomes and sex chromosomes Classification of abnormality Affected Chromosome /number Description Metafemale syndrome Numerical abnormality Sexual aneuploidy 47 Chromosome x Wolf-hirschhorn syndrome Structural abnormality Deletion 46 Chromosome 5 Structural abnormality Deletion Chromosome 11 Pallister-Killian syndrome Chromosome 12 47 Chromosome 13 Isodicentic 15 syndrome 47 Numerical abnormality autosomal aneuploidy 47 Chromosome 18 Cat eye syndrome Chromosome 22 Down syndrome 47 With oblique eyes Numerical abnormality Sexual aneuploid Also called as criminal syndrome Turner syndrome 45 45 Numerical abnormality sexual aneuploid Can not survive long…A woman who sought genetic counseling is found to be heterozygousfor a chromosomal rearrangement between the second andthird chromosomes.

- In humans, chromosome 16 sometimes has a heavily stained area near the centromere. This feature can be seen in a microscope, but otherwise has no effect on the phenotype of the person carrying it. When such a “blob" exists on a given copy of chromosome 16, it is a constant feature of that chromosome and is inherited. A couple conceived a child, but the fetus had multiple abnormalities and was miscarried. e.g., The fetus had three copies of chromosome 16, where 2 of the 3 copies of chromosome 16 had large blobs. Both of the mother's copies of chromosome 16 lacked blobs, but the father was heterozygous for blobs. The fetus was formed from a fertilization event that included a gamete produced by the in which nondisjunction occurred during the meiotic division. Select an answer and submit.
