∙ 10y agoTaking sexually reproducing plants for example, and keeping it simple, one can start with a plant possessing, say, 24 chromosome pairs going though replication and ending up with this replication producing 48 chromosome pairs; something not uncommon in plants. Now this new plant can not reproduce with the founding population that has 24 chromosome pairs, so selfing may be a way that this plant can reproduce and begin a 48 chromosome pair population and a new species of plant. Remember, more chromosomes and more protein product leading to duplication, mutation and new traits in our new population.

Polyploidy instantly results in a new plant species because it?
changes a species' number of chromosomes.:) no problem
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 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.
What species depends on its ability to produce new members?
All species of organism depend on their ability to produce new members. Without reproduction, the species would die out.
Do members of a species do not have the ability to produce new individuals?
yes
Polyploidy instantly produces a new plant species because it does what?
no
What is one specific example of observed evolution in a species?
Polyploidy in plants leading to new species.
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.
How many generations does it take to develop a new plant species by polyploidy?
One

What advantage does polyploidy give to a plant breeder?
It produces bigger and more flourishing crops and breeders could use the polyploidy to breed other plants and make them produce more food which would result in a lot more money for the breeders and sellers.
What species depends on its ability to produce new members?
All species of organism depend on their ability to produce new members. Without reproduction, the species would die out.
What has the author M L Kapoor written?
M. L. Kapoor has written: 'Studies on induced polyploidy and mutagenesis in some hardwood tree species' -- subject(s): Polyploidy, Breeding, Trees
Why is polyploidy a disadvantage to animals?
Polyploidy occurs with the organism has double the normal set of chromosomes. In plants this can produce larger more viable plants, but it animals this is an abnormal mutation and often fatal.
Is a kiwifruit a polyploidy?
Yes, kiwi fruit is a polyploidy.
