To explain:
The requirement to use genetic testing to check the disease in an embryo before the technique of the in-vitro fertilization, analysis of the embryo for testing to check for traits unrelated to the diseases. The analysis of the feasibility of performing the genetic tests and to draw a line of conclusion for the genetic tests which are acceptable and which are not.
Introduction:
The genetic testing by the procedure of amniocentesis is done to analyze the diseases in the embryo. In this technique, a small amount of amniotic fluid is extracted from the embryo sac layer inside the uterus of the mother and diagnosed for the pre-natal diseases. The technique of in-vitro fertilization is used for fertilizing the egg with a sperm in a test-tube and implanting the egg in the uterus of the mother at the eight-celled stage.

- Which of the following genetic changes would be passed from parent to child? A duplication of chromosome 21 during mitosis in a pancreas cell The addition of a chromosome in an egg cell A mutation in a skin cell caused by UV light A translocation in a nonhomologous pair of chromosomes in a liver cellarrow_forwardEdward’s syndrome in humans (trisomy 18) is characterized by which genetic feature? it involves a duplication of the entire genome it involves a deletion of one chromosome it involves a deletion of one gene it involves a duplication of one gene it involves a duplication of one chromosomearrow_forwardA 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?arrow_forward
- Mitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction. What would be a problem if an organism tried to use mitosis for sexual reproduction instead of meiosis? Mitosis Parent cell Meiosis Parent cell DNA replicates DNA replicates 2 daughter cells 2 daughter cells 4 daughter cells U.S. National Library of Medicine (Level 3) étv МacBook Air DII DD 80 888 F7 F8 F9 F10 F4 F5 F6 F2 F3 23 $ & 3 4 9. 7 8 9 Y F H J K L C V M B Earrow_forwardWhy are the chromosomes replicating?

- An organism’s traits are determined by the specific combination of inherited ______. a. cells b. genes c. proteins d. chromatidsarrow_forwardYou are a genetic counselor, and your patient has asked to be tested to determine if she carries a gene that predisposes her to early-onset cancer. If your patient has this gene, there is a 50/50 chance that all of her siblings inherited the gene as well; there is also a 50/50 chance that it will be passed on to their offspring. Your patient is concerned about confidentiality and does not want anyone in her family to know she is being tested, including her identical twin sister. Your patient is tested and found to carry a mutant allele that gives her an 85% lifetime risk of developing breast cancer and a 60% lifetime risk of developing ovarian cancer. At the result-disclosure session, she once again reiterates that she does not want anyone in her family to know her test results. a. Knowing that a familial mutation is occurring in this family, what would be your next course of action in this case? b. Is it your duty to contact members of this family despite the request of your patient? Where do your obligations lie: with your patient or with the patients family? Would it be inappropriate to try to persuade the patient to share her results with her family members?arrow_forwardThe fused cell is cultured and is implanted as a multi-celled embryo. During the step where the fused cell begins dividing normally, the cells of the future clone undergo a. fertilization b. gene splicing c. meiosis d. mitosisarrow_forward

It is a central nervous system neurodegenerative disease that most often affects infants, though older children and adults can have late-onset forms of the disease. The defective gene prevents the body from making a protein called hexosaminidase A. Without, hexosaminidase A, chemicals called gangliosides build up in the nerve cells of the brain, destroying brain cells.A couple has one daughter with Tay-Sachs disease and three other unaffected children. Neither the mother, nor father, nor any of the biological grandparents of the affected daughter have had the disease. Tay-Sachs disease most likely demonstrates what type of inheritance? Pedigree information regarding the incidence of Tay-Sachs within a family is depicted above. The row below that indicates the genotypes of individuals II-1, II-2, and III-1 is Select one: a.
