- The centromere Group of answer choices A is a group of proteins that attach to the kinetochore. B is not present on the chromosomes of the daughter cells until anaphase. C is a region of DNA where sister chromatids associate with one another and where the kinetochore forms D is a group of proteins that attach to the mitotic spindle. E is a region of DNA where sister chromatids associate with one anotherNeed help with the diagram The STR DNA marker DS11 is located on the p arm of the chromosome #8 in humans. Molecular analysis has shown that Charlie Chaplin is a heterozygote for the STR marker (genotype DS11A and DS11B) Using this knowledge, provide a diagram of meiosis showing only the movements of chromosome 8 (assume no nondisjunction). Throughout, indicate where the marker may be found (in other words, label the chromosome to show where the STR markers can be found. please only show the chromosomes at interphase, metaphase 1, end of meiosis 1, metaphase 2, and end of meiosis 2.Select true or false for each of the following statements regarding metaphase I. Homologous chromosomes are connected only at the centromeres. Answertruefalse Homologous chromosomes are aligned at the metaphase plate. Answertruefalse The paternal chromosomes are aligned on one side of the metaphase plate and the maternal chromosomes are aligned at the other. Answertruefalse In a cell with 4 chromosome pairs, there are 16 different ways to align the tetrads. Answertruefalse Homologous chromosomes are independently assorted. Answertruefalse
- Select 5 correct answer(s) Question 5 options: A) In fruit flies, sex is determined by the ratio of the number of X chromosomes to sets of autosomes.. B) In mammals, sex is determined by a single gene on the X chromosome. C) Sister chromatids are held together by unreplicated centromeres. D) Crossovers, in combination with sister chromatid cohesion, physically connect homologs at metaphase of meiosis I. E) Homologous chromosomes have identical DNA sequences. F) In mammals, sex is determined by a single gene on the Y chromosome. G) At mitosis, microtubules attach to kinetochores located at telomeres to segregate sister chromatids to opposite poles. H) Chromosomes that fail to have at least one crossover have an increased risk of meiosis I…At the end of Meiosis II in human cells (specifically in males, for example), how many gametes are made from one original parent cell, how many chromosomes are in each gamete, and what is each chromosome made of (that is, if you compared, say, chromosome #1 in a gamete with the two #1 chromosomes the person inherited from his parents)?13.Which among the following statements is INCORRECT? A. All statements are correct B.Only one of the two gene copies present in an organism is distributed to each gamete (egg cell / sperm cell) because of the separation of homologous chromosomes and sister chromatids during meiosis. C. If a cross produces 100% heterozygous genotype, then all of the offspring will exhibit the dominant allele D.The arrangement of chromosomes in metaphase I and metaphase II in Meiosis is not random, therefore, the inheritance of a trait will not affect the inheritance of the other trait
- 6. Consider your btoehr and your son. a. If you are female, will your brother and your son have essentially identically Y chromosomes? Explain your answer. b. If you are male, will your brother and your son have essentially identical Y chromosomes? Explan your answer.Hi, could your please answer this question? I'm so confused. The following diagram (picture added) shows 2 pairs of autosomal chromosomes in a karyotype of a biological woman. Based on the karyotype, a genetic counselor determined that there is evidence that a translocation occurred between two non-homologous chromosomes. The other 21 pairs of chromosomes are NOT shown in this diagram. Assume no chromosomal aberrations occurred in the other chromosomes. As a student-researcher, what would be your answer if the genetic counselor asks you if you can determine whether the translocation occurred in a somatic cell, germ-line cell, or whether this can even be determined from the figure? provide the reasoning for your answer.Can you guys complete this assignment? The instructions say “You will track and draw chromosome of a diploid organism through all the stages of mitosis. Make sure to replicate the chromosomes when appropriate and separate the chromosome pairs or the chromatids at the correct stages. Also, make sure you draw the alleles for genes A and B on the chromatids in every stage. Fill in the genotypes where indicated on the empty boxes.”
- no need to explain i just need help if its a,b,c or d. 1.) The number of sister chromatids in a chromosome at metaphase is a.) two in mitosis and one in meiosis b.) one in mitosis and two in meiosis c.) two in mitosis and two in meiosis d.) two in mitosis and four in meiosis 2.) In a Mendelian monohybrid cross with dominance, which answer represents the convention used to assign letters to form a genotype? a.) The dominant trait is represented by an uppercase letter, while the recessive trait is represented by lowercase of the same letter. b.) The dominant trait is represented by a lowercase letter, while the recessive trait is represented by uppercase of the same letter. c.) Both traits are expressed by uppercase letters. d.) Both traits are expressed by lowercase letters. 3.) A gene with more than two alleles is said to have multiple alleles. In humans a single gene with multiple alleles determines a person’s blood type. If an individual with blood type A mates with a person who…Meiosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of meiosis. Make sure you label the alleles for genes on the chromosomes the whole way through - every chromatid should have labeled alleles. For meiosis, both crossing over and independent assortment can occur. For the purpose of this exercise, assume that there is a single crossover event on the long chromosome between the A and D genes. Only show crossing over after its fully occured. There are no crossover events on the short chromosome. Regarding independent assortment, there are two possible outcomes in meiosis if there are two homologous pairs of chromsomes. Include both independent assortment possibilities - one on the left side and one on the right. Fill in the possible gamete genotypes for each outcome. If you do this correctly you should end up with 8 different types of gametes. Image attached for genotypes and alleles. Give me a full explaination of each of…Meiosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of meiosis.
