What is a chromosome mutation?
mutation is a permanent change in the DNA sequence of a gene and can alter the amino acid sequence of the protein encoded by the gene..
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).
Since the traits for hemophilia are carried on the X chromosome and not the Y, it is more probable for females to have a chromosome with the mutation. Since the mutation is considered recessive and males only have one X chromosome, they are more likely to portray the phenotype for hemophilia than their female counterparts.
An autosomal mutation is a mutation on any chromosome except the X or Y. These types of mutations can show up in either men or women with equal chances. A sex-linked mutation is generally on the X chromosome, as men only have one it gives them a higher chance of having a disorder caused by the mutation.
About 5-8 percent of males, but less than 1 percent of females, are color blind in some way or another, whether it be one color, a color combination, or another mutation. The reason males are at a greater risk of inheriting an X linked mutation is because males only have one X chromosome (XY, with the Y chromosome being significantly shorter than the X chromosome), and females have two (XX); if the women inherit a…
Genetic mapping is mapping genes to a specific location on a chromosome. therefore the purpose is that it helps to tell where on the chromosome a mutation is. For example if scientists find were on a chromosome a gene for a certain mutation, they can conduct gene therapy to replace it with a normal version of that gene. Basically it just tells scientists the location of a mutation so they can fix it more efficiently.
No. The X chromosome with the mutation will look no different than any other X chromosome. In order to see the mutation you would have to actually examine the base pairs and sequences. A single reversal, translation, deletion, or mutation of any kind within the specific segment of code can result in hemophilia. This will not result in an overall change in appearance of the chromosome.
