- Why is karyotyping significant in understanding chromosomal abnormalities? Short essay only thanks please the main answerA company that offers PGD terms an embryo “normal and healthy” if it has 46 chromosomes. Why is this statement misleading? , Two famous male actors had twins using a surrogate mother who carried two embryos that hadbeen fertilized in vitro, one with one man’s sperm and the other with the other man’s sperm. In terms of genetics, how closely are the babies, a boy and a girl, related to each other if they have different fathers?Gene duplications are commonly observed in genomes of higher eukaryotes including humans. Which of the following cellular events are most likely responsible for this observation and the formation of tandem repeats or pseudogenes? Question 16 options: crossing over during meiosis selective translocation unequal crossing over between autosomes involving Alu sequences unequal crossing over between homologous chromosomes involving LINE sequences copying mistakes during DNA replication
- the deletion of which chromosome causes obvious morphological and mental defects in the organism, such as microcephaly, strabismus, major mental retardation and is known as the 'cri-du-chat' syndrome?Two nonhomologous chromosomes have the following segments, where * represents the centromere: *ABCDEFG , *RSTUVWX. Name the type of chromosomal rearrangements that would produce each of the following chromosomes. *ABABCDEFG , *ABCD , GFEDCBA*RSTUVWX , *RSWVUTX , *ABCWX , *RSTUVDEFG . Which of these types of abnormalities are most likely embryonic lethal and which ones are not usually a problem for the individual carrying them? Briefly explain why.The following diagram represents two nonhomologous chromosomes: A B • C D E F G R S • T U V W X What type of chromosome mutation would produce of the following groups of chromosomes? Q. A B • C D R S • T U V W X E F G
- The following diagram represents two nonhomologous chromosomes: A B • C D E F G R S • T U V W X What type of chromosome mutation would produce of the following groups of chromosomes? Q.A B • T U V F G R S • C D E W XA colleague e-mails you saying that she has identified an interesting chromosome variation at 21q13. In discussing this discovery with a friend who is not a cytogeneticist, explain how you would describe this location, defining each term in the chromosome address 21q13.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.
