A karyotype is a picture of the chromosomes in a cell. For example, a human cell has 46 chromosomes. In the karyotype, 23 pairs of chromosomes will be shown (23 x 2 = 46). A karyotype can show different types of mutations, depending on which chromosome it affects. For example, Down Syndrome is a trisomy in chromosome 21, so there will be THREE instead of two chromosome 21s. You can research more mutations shown by chromosomes in a karyotype.
No. But they are necessary for mutations to arise. Likewise, they are also necessary in order for mutations not to arise.
There are a few mutations caused by entire chromosome changes. The times the number of chromosome can change can occur when the duplicated chromosomes pull apart and then produce a cell missing a chromosome or having an additional one. For example, XO or XXX or XXY. These are the sex chromosomes where XO means that either the second X is missing, or the Y is missing. Normal would be XX (female) or XY (male). These individuals are able to live with these added or deleted genes. All other missing or additional chromosomes are not compatible with life.

crossing over of chromosomes, indepependent segregation of chromosomes and mutations
Yes, somatic mutations can occur in sex chromosomes. These mutations can affect the genes located on the X or Y chromosome, leading to genetic changes in somatic cells, which are not passed on to offspring. Somatic mutations on sex chromosomes can impact an individual's health and development.
They are both mutations of chromosomes
true
Two are insertion mutations and deletion mutations.

dominant disorder is caused by mutations in genes on the x chromosomes.
