They isolated three genes on chromosome 15 -- GABRA5, GABRB3 and GABRG3
A trisomy. A monosomy is when there is only one of a chromosome. A trisomy is when there are three of a chromosome. In Klinefelter's syndrome, there are three sex chromosomes.
21 autosomes becasue chromosome 21 has three chromosomes and chromosome 23 is the sex chromosome - the allosome
21 st chromosome it is also call Trisomy 21 because the 21st chromosome has three instead of the normal two.
chromosome 21
trisomy!
The presence of three copies of a chromosome is known as a trisomy. An example would be Trisomy 21, also known as Down Syndrome.
A trisomy is a condition in which a person has three copies of a chromosome instead of the usual two copies. A person can have full trisomy (three copies in every cell) or mosaic trisomy (three copies in some cells but not all).
In one kind of abnormal chromosome inheritance called Down syndrome, a child has three copies of Chromosome 21!
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
life was originated from three chromosome. three chromosome organism is the centromere of life. natural selection is much associated with gradual increase in chromosome due to effect of elcrtromagnetic radiation.
