Having additional or missing chromosomes can have a variety of effects, ranging from mild to fatal. For example, females missing an X chromosome (they would normal have two) suffer from a condition known as Turner syndrome, which can cause problems like stunted growth and infertility.
An example of a condition involving an additional chromosome is Trisomy 21, more commonly known as Down syndrome. In this instance, the individual has an extra 21st chromosome--they should have two, but instead have three. This tends to lead to growth defects and mental retardation.
More severe chromosome abnormalities can be fatal--some will result in miscarriage during fetal development.
What else can I help you with?
What happens if you have more or less chromosomes?
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).
What might be the effect of inheriting more than the normal number of chromosomes in a human?
The implications of too many or too few chromosomes from the normal chromosomes are birth defects. With too many chromosomes a child could have Down Syndrome. With too few chromosomes a child could have Turner Syndrome.
What happens during the first division of meiosis that does not happen in meiosis?
In Meiosis I: Separates homologous chromosomes In Meiosis II: Separates sister chromatids
A human cell may have more or less than 46 chromosomes as a result of nondisjunction a process in what?
A human cell may have more or less than 46 chromosomes as a result of nondisjunction, which is a process that occurs during cell division where chromosomes fail to separate properly. This can lead to an incorrect number of chromosomes in the resulting daughter cells.
Why is it important the the number of chromosomes is reduced when gametes are formed?
poo come out the bum
What happens if a person have more chromosomes?
If it had more chromosomes it will cause to down's syndrome

What happens to the chromosomes when more cells are produced?
As a new baby grows, more cell must be made. This happens by the process of cell division. Each new cell has its own set of chromosomes carrying exactly the same information as the original fertilized cell.

What happens if there are no more trees?
there will be less oxygen
Why are individual chromosomes more difficult to see during inter phase than during mitosis?
The individual chromosomes cannot be seen in interphase because they haven't been condensed yet. That's what happens during mitosis so that it is easier to seperate them into new daughter cells. While in interphase, its called chromatin.
What is the process call when a human cell may have more or less than 46 chromosomes as a result of nondisjunction?
Chromosomes fail to separate during cell division (its in the lesson)
Some relatively simple eukaryotes such as the adder's tongue fern may have many more chromosomes than a more-complex eukarytoe such as a mammal what might this suggest about the size and organizatr?
Relatively simple organisms with more chromosomes might have smaller chromosomes containing less DNA. Also, some of the DNA in an organism's chromosomes may not carry information that is actually used by the organism.
What happens when polyploidy has taken place?
Polyploidy occurs in cells and organisms when there are more than two paired sets of chromosomes.
Why is it important the the number of chromosomes is reduced when gametes are formed?
