Are chromosomal abnormalaties confined only to certain parts of the body?

Answer 1

No, non disjunction can effect any chromosome of the 23 pairs so what ever genes or alleles are express from that chromosome will not be due to its absenece. So abnormal genetic mutations can occur anywhere.

Answer 2

If the chromosomal abnormality is inherited the most likely option is the it will be expressed everywhere. Depending on the precise abnormality some systems of the body may be more affected than others.

It's possible to have mosaic abnormalities in which case the abnormal cells are distributed throughout the body based on when the divergence occured, which usually leads to a less severe phenotype, but not always.

Answer 3

No. Chromosomal abnormalities originate in the development of sperm and egg cells. When a sperm cell and an egg cell combine (fertilization) their chromosomes are merged into one cell (a zygote.) This new cell will contain any chromosomal abnormalities that were already in place with either the sperm cell or the egg cell.

As the zygote develops, it will produce genetic copies of its chromosomes, and each copy will be part of a new cell. Those copies will form copies of their own, and so on. Every cell in the resulting organism (except for its own sperm or egg cells) will be a genetic copy of the original zygote, including any chromosomal abnormalities that may have been present.

Answer 4

No.
Genes control every part of the body.
Chromosomal abnormalities can involve all systems and organs of the body.

Answer 5

No. All of your DNA is in all of your cells, but depending on which chromasome the abnormality is on, it will affect different parts of the body.

Answer 6

Yes, only the body parts that have CELLS are open to suffer from chromosonal abnormalities. Duh:)
