This is the condition of polyploidy. Plants speciate by this method quite often.
The condition in which an organism has complete extra sets of chromosomes is called polyploidy. This condition can cause a number of severe birth defects. Most do not live a full lifespan for their species.
Polyploidy is the condition in which an organism has extra sets of chromosomes. It can be defined as a chromosomal alteration in which the organism posses more than two complete chromosome sets. Classified as an accident in cell division.
Polyploidy allows the formation of new species derived from different ancestors. Polyploid is the condition in which an organism has extra sets of chromosomes.
Polyploidy is the heritable condition of possessing more than two complete sets of chromosomes. Polyploids are common among plants, as well as among certain groups of fish and amphibians.
The answer is a Polyploidy
polyploidy is a condition where an organism has extra sets of chromosomes. polyploid plants are often larger and stronger than diploid plants
Trisomic condition in which there is one extra chromosome on an autosome. For eg. Down's Syndrome
It depends on which chromosomes were present as to what the abnormality would be, if any. If they were missing one or had one extra there would be developmental abnormalities.
21, the condition is also referred to as trisomy 21.
if you have an extra pair of 21 chromosomes, you will have down syndrome. if you have a 23 pair of chromosomes then i believe that you will be super human, (very fast, very strong, heals in seconds and will be almost invincible. When talking about down syndrome you don't get an extra pair of chromosomes, you get a single extra chromosome on the 21 pair of chromosomes.
An abnormal number of chromosomes is called aneuploidy. If a chromosome has 3 of its kind, it is trisomic. The exact condition depends on which gene has the extra chromosome.
The general term is aneuploidy. Some examples: Down Syndrome is a commonly known condition in which the person has an extra copy, making three, of the 21st chromosome. Others are Edwards Syndrome (an extra 18th) and Patau Syndrome (and extra 13th).
Chromosomal disorders can be observed in a human karyotype. It can show whether there are extra chromosomes, or missing chromosomes, or malformed chromosomes, or whether chromosomes have extra pieces, or missing pieces.
In sexual reproduction, two sexes are used to make the offspring. The "extra" chromosomes come from the sperm.
I am aware of three genetic disorders involving extra chromosomes. I know of none involving less chromosomes.
It doesn't affect chromosomes but it adds an extra 21st chromosome
No , it is caused by a single gene mutation .
