The difference between polyploidy and nondisjunction is that being polyploidy is a result of nondisjuction. When the metaphase II doesn't occur properly the homologous pairs will stay together. Leaving one cell with out that chromosome and with with an extra. Polyploidy has one too many chromosomes.

° Monosomic cells have only one copy of a particular chromosome type and have 2n − 1 chromosomes.
· Organisms with more than two complete sets of chromosomes are polyploid.
· This may occur when a normal gamete fertilizes another gamete in which there has been nondisjunction of all its chromosomes.
° The resulting zygote would be triploid (3n).

∙ 12y agoNondisjunction is the failure of one or more pairs of homologous chromosomes or sister chromatids to separate normally during nuclear division, usually resulting in an abnormal distribution of chromosomes in the daughter nuclei. Polyploidy, on the other hand, is a term used to describe cells and organisms containing more than two paired (homologous) sets of chromosomes.

What would be the ploidy of the viable gametes produced by a tetraploid individual if nondisjunction of all chromosomes occurred in meiosis you?
Sounds like it would be octoploid. Common in plant polyploidy.
What is an extra set of chromosome?
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.
The faillure of chromosomes to separate during meiosis is called?
Its called disconjunction. Sometimes it is so bad that they have a miscarriage or the following happens:Trisomy (extra chromosomeso have 47 chromosomes instead of 46)Down's syndrome (andextra number 21 chromosome)Klinefelter's syndrome (males with an extra X chromosome...XXY)
What types of organisms are polyploidy?
Polyploidy occurs in cells and organisms when there are more than two homologous sets of chromosomes. "occurrence of polyploidy suggests an evolutionary advantage of having multiple sets of genetic material for adaptive evolution"
What is nondisjunction in chromosomes and what is the result?
Nondisjunction is the addition or deletion of an entire chromosome. The result could be autism or downs syndrome
The condition in which a diploid cell has an extra chromosome is called?
Polyploidy is the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
What would be the ploidy of the viable gametes produced by a tetraploid individual if nondisjunction of all chromosomes occurred in meiosis you?
Sounds like it would be octoploid. Common in plant polyploidy.
Is a kiwifruit a polyploidy?
Yes, kiwi fruit is a polyploidy.

What are polyploidy and when is this condition useful?
Polyploidy allows the formation of new species derived from different ancestors. Polyploid is the condition in which an organism has extra sets of chromosomes.
What is it called when chromosomes don't separate correctly during meiosis?
Nondisjunction
What happens when polyploidy has taken place?
Polyploidy occurs in cells and organisms when there are more than two paired sets of chromosomes.
Is polyploidy fatal in animals?
porn
Is colon cancer nondisjunction?
no
Is fragile x syndrome a result of nondisjunction during meiosis?
yes . it is . nondisjunction is takes place during meiosis.
