1706677568 | The production of offspring with combinations of traits that differ from those found in either parent | Genetic recombination | 0 | |
1706691224 | Offsprings that have new combinations | Recombinant types | 1 | |
1706705188 | Break the physical connection between alleles of genes in the same chromsome | Crossing over | 2 | |
1706729451 | Ordered list of genetic loci along a particular chromsome | Genetic map | 3 | |
1706736699 | Genetic map based on recombination frequencies | Linkage map | 4 | |
1706743849 | Units that express distance between genes by 1% | Map units | 5 | |
1706768866 | Locate genes respect to chromosomal features, such as stained bands, that can be seen by microscope | Cytogenetic maps | 6 | |
1706783631 | Member of a pair of homologus chromosomes do not move apart properly during meiosis 1 sister chromatids fail to seperate during meiosis 2. One gamete receives two of the same type of chromosome and another gamete receives noncopy | Nondisjunction | 7 | |
1706797071 | Condition involving more than one chromsome | Aneuploidy | 8 | |
1706799742 | Aneuploidy zygote missing a chromosome is said to be a | Monosomic | 9 | |
1706809051 | If the zygote is triplet of chromsomes the aneuoploidy cell is | Trisomic | 10 | |
1706811229 | Example disorder of trisomy | Down syndrome | 11 | |
1706820700 | organisms that have more than ine complete chromosome sets in all somatic cells | Polyploidy | 12 | |
1706828940 | Errors of meiosis or damaging agents such as radiation can cause breakage of a chromosome, which can lead to four types of chsnges in chromosome structure | Deletion, duplication, inversion, translocation | 13 | |
1706830455 | Occurs when a chromosomal fragment is lost | Deletion | 14 | |
1706836559 | A deleted fragment may become attached as an extra segment to a sister chromatid, producing a | Duplication | 15 | |
1706842784 | A chromosomal fragment may also reattach to the original chromosome but in reverse orientation, producing an | Inversion | 16 | |
1706845917 | The fragment joins a nonhomologus chromosome, a rearrangement called | Translocation | 17 | |
1706862092 | Result of an extra chromsome 21, trisomy 21 | Down syndrome | 18 | |
1706868758 | Frequency of Down syndrome increases with the age of the | Mother | 19 | |
1706877976 | XXY, extra X chromosome in a male, tested abnormally small, sterile | Klinefelter syndrome | 20 | |
1706887468 | XYY males do not exhibit anywell defined syndrome but they tend to be | Taller | 21 | |
1706892351 | XXX females have unusual physical features other than being | Taller | 22 | |
1706898135 | Monosomy X, women are sterile, sex organs dont mature, | Turner syndrome | 23 | |
1706906476 | Deletion of chromosome 5, intellectually disabled, small head unusual facial features, cry of a distressed cat | Cry of the cat | 24 | |
1706933970 | Translocation have been implicated in certain cancers, this disease occurs when a reciprocal translocation happens during mitosis of cells that will become white blood cells. In these cells, the exchange of a large portion of chromosme 22 with a small fragment of chromosome 9 produces a much shortened, easily recognized chromosome 22 called philadelphia chromosome. Such angene causes cancer by activating a gene that leads to uncontrolled cell cycle progression | Chronic myelogenous leukemia (CML) | 25 | |
1706945501 | Which gene on the y chromsome is required for development in the tested | SRY | 26 | |
1706948450 | In the abscence of SRY the gonads develop into | Ovaries | 27 | |
1706951172 | A gene located on either sex chromsome | Sex linked gene | 28 | |
1706952844 | Genes located on y chromsome | Y linked genes | 29 | |
1706954678 | Genes located in the x chromsomes | X linked genes | 30 | |
1706957940 | Disorder that affects males by aborogressive weakening of muscles and loss of coordination. Affected individuals ratelyblive passed their early 20's. Due to abscence of dystrophin in anlocus of the x chromosome. | Duchenne muscular dystrophy | 31 | |
1706959776 | X linked recessive disorder defined bybtue absence of onenor more of the proteins required for blood clotting. When injured, bleeding is prolongued because firm clot is slow to form | Hemophilia | 32 | |
1706961543 | X chromosome inactivated during early embrionic development becoming highly condensed into a | Barr body | 33 | |
1706964281 | A single gene on a sex chromosome | Sex linked gene | 34 | |
1706966303 | Two or more genes on the same chromosome that tend to he inherited | Linked genes | 35 | |
1706975341 | Variation in phenotype depending on whether allele is inherited from a male or a female parent | Genomic imprinting | 36 |
