2. a chromosome that determines the sex of an individual(We can see that this karyotype codes for a male) 3. Any chromosome that is not a sex chromosome 4. a trait that is determined by a gene found on one of the sex chromosomes, such as the X chromosome or the Y chromosome in humans 5. One of a pair of genes that tend to be inherited together 6. A diagram of gene positions on a chromosome 7. in chromosome mapping, an increment of 1 percent in the frequency of crossing-over 8. mutation that occurs in an organism's gametes 9. A mutation that occurs in a body cell 10. a gene or chromosomal mutation that influences the development of an organism in such a way that the organism cannot survive 11. Loss of a part of DNA from a chromosome 12. a kind of mutation in which the order of the genes in a section of a chromosome is reversed 13. an exchange of chromosome parts 14. meiosis in which there is a failure of paired homologous chromosomes to separate 15. gene mutation involving changes in one or a few nucleotides 16. A mutation in which a nucleotide or a codon in DNA is replaced with a different nucleotide 17. mutation that shifts the "reading" frame of the genetic message by inserting or deleting a nucleotide 18. a mutation in which one or more nucleotides are added to a gene 19. A diagram that shows the occurrence of a genetic trait in several generations of a family 20. an inactive substance that is a vehicle for a radioactive tracer of the same substance and that assists in its recovery after some chemical reaction 21. an abnormal condition that a person inherits through genes or chromosomes 22. of or relating to an inheritable character that is controlled by several genes at once 23. characters that are influenced strongly both by the environment and by genes 24. genes with three or more alleles 25. situation in which both alleles of a gene contribute to the phenotype of the organism 26. one allele is not completely dominant over the other allele 27. an autosomal trait that is influenced by the presence of male or female sex hormones 28. A human genetic disease caused by a dominant allele; characterized by uncontrollable body movements and degeneration of the nervous system; usually fatal 10 to 20 years after the onset of symptoms. 29. Technique that allows a physician to remove from the amnion, the sac that surrounds the fetus, between the 14th and 16th week of pregnancy 30. Sampling of cells derived from the zygote that grow between the mother's uterus and placenta between the 8th and 10th week of pregnancy 31. Guidance for prospective parents on the likelihood of genetic disorders in their future children 32. The insertion of working copies of a gene into the cells of a person with a genetic disorder in an attempt to correct the disorder 33. the exchange of genetic material between homologous chromosomes during meiosis can result in genetic recombination
