Individuals with additional chromosomes beyond the normal 2N complement are generally nonviable and the few exceptions that result in a live offspring are still profoundly affected in a negative way. he presence of additional sex chromosomes often have less profound effects.
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.
Depends on what chromosome. Usually if you have an excess of genetic information it's not as harmful as a loss of genetic information. For example, Down Syndrome is trisonomy 21 - an extra chromosome #21.
The most likely scenario is that an organism with this type of flaw would die as a conceptus also termed EED (early embryonic death). The chances of anything approaching viability are so low as to be near zero...and that is only because one can never say never since there may be some stray species out there that may be fine with that much additional DNA
If you have too many chromosomes then you will gain a genetic disorder
It would be bad if you had less than 45 chromosomes, as a human body has 46 chromosomes.
dead kid unless the extra is number 21, then down syndrome.
Trisomy (three chromosomes) generally results in non-viable or developmentally impaired offspring.
Meiosis is a process of cell division that produces gametes in organisms that sexually reproduce. A gamete having more than one complete set of chromosomes cannot be produced by meiosis.
to be honest i think that the chromosomes trvel thorugh and do someother stuff
Each duplicated chromosomes would be pulled to one side or the other spindle poll, which is what happens in anaphase 1 of meiosis.
No there isn't. Humans are much more complex than a fern, yet the Adder's Tongue Fern has 1262 chromosomes and a human has only 46. It also doesn't work the other way either (more complex organisms having less chromosomes) for fruit flies have 8 chromosomes and dogs have 78. Also, chimpanzees have the same number of chromosomes as potatoes and, surely, they are on different complexity levels.
Sister chromatids are replicated DNA and are identical. Homologous chromosomes are not, as one comes from the mother and the other comes from the father.
one more than humans
If you have one additional pair of CHROMOSOME 23, you have DOWN SYNDROME.If a person has fewer than 46 chromosomes, they will die. With more than 46 chromosomes, it depends on the chromosome type , but mostly disorders or syndromes will occur. Death is also a possibility in this case.AnswerThe condition wherein the number of chromosomes in a individual is more or less than the expected number of chromosomes is called aneuploidy.Examples include Down's Sydrome (three sets of chromosome 21), Klinefelter's syndrome (one extra X chromosome in males), Turner's syndrome (one X chromosome less in females), Edward syndrome (extra chromosome 18).
one set of chromosomes
It is certainly possible to have more than 46 as in Trisomy 21 (or down syndrom) where "one cell has two 21st chromosomes instead of one, so the resulting fertilized egg has three 21st chromosomes".
Meiosis is a process of cell division that produces gametes in organisms that sexually reproduce. A gamete having more than one complete set of chromosomes cannot be produced by meiosis.
The number of chromosomes of a species has little to do with the complexity of the organism or the amount of DNA. The reason for this is, chromosomes are known to break and form two or more new chromosomes, or fuse into one. The chromosomes of the potato and the potato lineage may have undergone many such changes, and the human lineage may have undergone a different series, resulting in the potato having more chromosomes.
Yes - for example, the Alfalfa plant has 32 chromosomes.

the synapsis and crossing over of homologous chromosomes
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.

males have only one X chromosomes
