There are very few animals with polyploidy like salamanders. Why is it that polyploidy is so uncommon in animals? On the other hand, there are numerous examples of polyploid plants. If it is something to do with the gene dosage, how does it not affect plants?
Please have a look at this link.

One of the factor influencing Polyploidy in plants is the crop ddomestication process carried out by humans through million of years
Plants are fixed in their bed. Therefore, they are constantly influenced by variable factors of their environment which may cause more changes on their karyotype.
Moreover, most of plant species produce lots of seeds through sexual regeneration by which chance of genomic changes would be increased.
A new genotype of plant species is not dependent on its parental plant. whereas, a new form of an animal is highly dependent on its parents which might be even rejected due to its new form or shape.....
