Mutations in DNA that result in altered proteins can causehereditary diseases. Pedigree studies and genetic testing mayclarify the risk of disease. At the chromosome level, nondisjunctionduring meiosis can result in gametes with too few or too manychromosomes, most of which produce inviable offspring.Imprinting refers to inactivation of alleles depending on whichparent the alleles come from; offspring in whom imprinting occursappear haploid for the affected gene even though they are diploid. During spermatogenesis, is there any difference in outcome between first- and second-division nondisjunction?
Genomic imprinting refers to the inheritance of: Question 16 options: Gamete specific DNA methylating marks during meiosis. All epigenetic marks during mitosis. DNA methylating marks during mitosis. All epigenetic marks during meiosis. Gamete specific DNA methylating marks during mitosis.
What aspect of chromosome behavior most clearly accounts for Mendel's law of segregation? Movement of sister chromatids to opposite poles at anaphase Il of meiosis. Movement of homologous chromosomes to opposite poles at anaphase I of meiosis. Crossing over between homologous chromosomes during prophase I of meiosis. Replication of chromosomes prior to meiosis. Independent alignment of different homologous pairs on the metaphase I spindle.
Which of the following chromosomal rearrangements usually results in normal meiosis? translocation homozygote translocation heterozygote paracentric inversion heterozygote pericentric inversion heterozygote
Which of the following statements is true regarding the phenotypic effects of inversions? Select ALL that apply. Heterozygotes are often healthy individuals because these mutations do not impact the dosages of any genes Heterozygotes often exhibit reduced fertility, because translocated and wild-type chromosomes do not separate correctly during meiosis II Homozygotes are often healthy individuals because these mutations do not impact the dosages of any genes Heterozygotes often exhibit reduced fertility, because crossing over between inverted and wild-type chromosomes in Meiosis I results in inviable gametes Heterozygotes often exhibit reduced fertility, because crossing over between inverted and wild-type chromosomes in Meiosis Il results in inviable gametes
Which of the following is false regarding Down Syndrome? O can be caused by a Robertsonian translocation which is the fusion of the q arm of chromosome 21 with the q arm of chromosome O can be caused by a nondisjunction event O can be caused by equal exchange of chromatids during crossing over O Down syndrome individuals could possibly have normal children
Hi, I'm having some trouble with this practice problem from my study guide. If anyone can explain it it would be very helpful! Sometimes nondisjunction will occur in a parent that has normal chromosome numbers and result in an offspring that has abnormal number of chromosomes. The phenotype of the affected offspring will often allow geneticists to determine in which parent and during which division of meiosis the nondisjunction occurred. In each of the examples below, assume the parents have a normal diploid chromosome complement. EXAMPLE 1: A man with the X-linked dominant condition “brown tooth enamel” and a woman with normal tooth enamel produce a son with brown tooth enamel. Let’s call the allele for brown tooth enamel “XB” and normal tooth enamel “Xb”. In which parent did the nondisjunction occur? Explain and/or illustrate Did nondisjunction occur at meiosis I or II? Explain and/or illustrate. What sex chromosomes are in the child’s somatic cells? EXAMPLE 2: The parents in the…

Which statement about the relationship between genetic map and physical map is FALSE? The correlation between Genetic map distance and Physical map distance is not absolute. Roughly speaking, for two genes on the same chromosome, the bigger their genetic map distance is, the bigger the physical map distance is. The genetic map is in a way a distorted picture of the physical map. 1 genetic map unit (1cM) always correlates with a certain distance on the physical chromosome.
crossing over within a pericentric inversion produces chromosomes that have extra copies of some genes and no copies of other genes. The fertilization of gametes containing chromosomes with duplications or deletions often result in children with syndromes characterized by developmental delay, intellectual disability, abnormal development of organ systems, and early death. Maarit Jaarola and colleagues examined individual sperm cells of a male who was heterozygous for a pericentric inversion on chromosome 8 and determined that crossing over took place within the pericentric inversion in 26% of the meiotic divisions (M. Jaarola, R. H. Martin, and T. Ashley. 1998. American Journal of Human Genetics 63:218–224). Assume that you are a genetic counselor and that a couple seeks counseling from you. Both the man and the woman are phenotypically normal, but the woman is heterozygous for a pericentric inversion on chromosome 8. The man is karyotypically normal. What is the probability that this…
