Inherited problems
| Question | Answer |
|---|---|
| Euploid cells | Cells with a normal number of chromosomes |
| Polyploid cells | Cells with more then the diploid number of chromosomes |
| Tripliody cells | Cells with three copies of each chromosome |
| Tetraploidy | A Cell with 92 chromosomes |
| What is the difference between polyploidy and Aneuploidy? | Aneuploidy refers to a numerical change in part of the chromosome set, whereas polyploidy refers to a numerical change in the whole set of chromosomes. |
| Aneuploidy | A cell that does not contain a multiple of 23 chromosomes |
| Monosomy | A cell with only one copy of its chromosome |
| Trisomy | A cell with three copies of the one chromosome |
| Autosomal aneuploidy | Aneuploidy of any chromosome that is not a sex chromosome |
| Sex chromosome aneuploidy | Aneuploidy of chromosomes X and Y |
| Partial trisomy | A cell which has an extra portion of a chromosome |
| Down syndrome | Autosomal trisomy of chromosome 21 |
| Trisomy X (XXX) | Common sex chromosome aneuploidy in females: they inherit three X chromosomes instead of two, causing no overt physical abnormalities, but can cause sterility, menstrual irregularity, or mental retardation. |
| Monosomy X (X) | Chromosome disorder of females from inheriting only one X chromosome. Results in Turner Syndrome, characterized by short stature, webbing of the neck, widely spaces nipples, reduced carrying angle of the elbow, and underdeveloped breasts. |
| Klinefelter Syndrome | Chromosome disorder of males from inheriting two X chromosomes and 1 Y chromosome. Causes sterility, female-like breasts, high pitched voice, mental retardation. |
| Cri du chat syndrome | Genetic defect causes by deletion of part of the short arm of chromosome 5. Characteristics include, a cry "like a cat", low birth weight, severe mental retardation, microcephaly, & heart defects. |
| A deficiency of genetic material is _____ harmful then excess | more |
| Inversion | When two break take place on a chromosome followed by reinsertion of the missing fragment at its original site, but in an inverted order. Called "balanced" alterations. |
| Translocations | The interchange of genetic material between nonhomologous chromosomes. |
| Reciprocal translocation | When two different chromosomes break and exchange information |
| Robertson Translocation | The long arms of two nonhomologous chromosomes fuse at the centromere, forming a single chromosome. |
