1566314389What are the 2 possible karyotypes for spontaneously aborted human fetuses if they where tetraploid?92,XXXX , 92,XXYY13
1566314390This is an individual made up of 2 or more cell lines, each with a different chromosome number and or a different chromosome complement.Mosaic14
1566314391A large number of spontaneously aborted fetuses and stillborns are mosaics of diploid and polyploid condition. What is their karyotype.46,XXX/69,XXX15
1566314392When indicating the chromosome make-up of a mosaic, the different cell lines are separated by what?Slash (/)16
1566314393What kind of human chromosome has been found in the trisomic condition in spontaneously aborted fetuses?All17
1566314394Which additional chromosomes will always cause the fetus to abort if it already has a complete set of chromosomes?1-7, 10-12, 1618
1566314395In most infants that have an extra chromosomes, it will be one of 4. What are the 4 most common additional chromosomes.Extra Sex Chromosome, Trisomy 21, Trisomy 18, Trisomy 1319
1566314396The only monosomic individuals that survive are those that have what single chromosome?X Chromosome20
1566314397Give 3 examples of aneuploidy involving the sex chromosomes.Klinefelter Syndrome (XYY males), Turner Syndrome, Poly-X Females21
1566347226Give 3 examples of aneuploidy involving the autosomes.Down Syndrome, Edwards Syndrome, Patau Syndrome22
1566347227A group of abnormalities that occur together and which characterize a particular disease.Syndrome23
1566347228Individuals whose sex chromosomes deviate by 1 from what is normal may have ________ intelligence or may be ________ _________.Normal, Mentally Retarded24

1566347231These are constructed to determine if numerical or structural chromosomal adorations are present.Human Karyotypes27
1566347232What is another name for a chromosome adoration?Chromosome Mutation28
1566347233These are constructed in order to make comparative studies of chromosomes of different species.Karyotypes29
1566347234The chromosome composition of a somatic cell of an individual in which pictures of the chromosomes are arranged in a standard sequence.Karyotype30
1566347235A camera is attached to a microscope and a photograph is taken of a ruptured stained cell in what phase?Metaphase31
1566347236Chromosomes are shortest and thickest at this stage of mitosis.Metaphase32
1566347237The chromosomes of a cell depicted in one the photographs are cut apart and are arranged in matching pairs according to ________ from the ________ to the ______ of the autosomes followed by the sex chromosomes.Lenght, Longest, Shortest33
1566347238In the past geneticists placed the austosomes into 7 groups instead of numbering them, what where those groups called?A, B, C, D, E, F, G34
1566347239Why did geneticists place autosomal chromosomes into 7 groups in the past?Not always sure if they paired them correctly35
1566347240This group is made up of very long metacentric chromsomes, chromosome pairs 1, 2, and 3.Group A36
1566347241This group is made up of long submetaentric chromosomes, chromosome pairs 4 and 5.Group B37
1566347242This group is made up of medium length submetacentric chromosomes, chromosome pairs 6, 7, 8, 9, 10, 11, and 12.Group C38
1566347243This group is made up of medium length acrocentric chromosomes with satellites, chromosome pairs 13, 14, and 15.Group D39
1566347244This group is made up of short submetacentric chromosomes, chromosome pairs 16, 17, and 18.Group E40
1566347245This group is made up of metacentric chromosomes that are shorter than chromosomes of group E, chromosome pairs 19 and 20.Group F41
1566347246This group is made up of very short acrocentric chromosomes with satellites, chromosome pairs 21, and 22 (chromosome 22 is actually longer than chromosome 21).Group G42

1566347249With these all of the chromosomes stain the same color and all parts of a given chromosome are the same color.Conventional Dyes45
1566347250These where developed in the late 1960s and improvements since them have made it possible for geneticists to accurately identify chromosomes.Banding Techniques46
1566347251Since banding patterns are unique and constant for each normal chromosome it is now possible to determine what 2 things?Which chromosome is missing, What part of a chromosome is abnormal and how47
