A girl and a boy were born to a young married couple. The girl is absolutely healthy. The examination of the boy's karyotype has shown 46 chromosomes. But one of the chromosomes of the 15th pair is longer than normal as a part of a chromosome from the 21st pair has joined it. How many autosomes and sex chromosomes are in the boy's karyotype? Name the type of the mutation. Is it possible to consider this pathology an inherited disorder?

A female patient 19 years old, whose symptoms areanemia and internal bleeding due to a massive buildupof leukemic white blood cells, is diagnosed withchronic myelogenous leukemia (CML). Karyotypeanalysis shows that the leukemic cells of this patientare heterozygous for a reciprocal translocation involving chromosomes 9 and 22. However, none of thenormal, nonleukemic cells of this patient contain thetranslocation. Which of the following statements istrue and which is false?a. The translocation results in the inactivation (loss offunction) of a tumor-suppressor gene.b. The translocation results in the inactivation (loss offunction) of an oncogene.c.
