Polyploidy is a
condition in
which the
cells of an
organism have more than two
paired sets of (homologous) chromosomes. Most
species whose cells have nuclei...
- all gr****es are polyploid. Many
animals are
uniformly diploid,
though polyploidy is
common in invertebrates, reptiles, and amphibians. In some species...

meiosis which is
sometimes called permanent odd
polyploidy,
although it can also
occur with even
polyploidy (e.g. in
tetraploids or hexaploids). Regardless...
-
ongoing discussion.
Rapid sympatric speciation can take
place through polyploidy, such as by
doubling of
chromosome number; the
result is
progeny which...

include ectopic recombination,
retrotransposition event, aneuploidy,
polyploidy, and
replication slippage.
Duplications arise from an
event termed unequal...
-
absence of mitosis,
which leads to
elevated nuclear gene
content and
polyploidy.
Endoreduplication can be
understood simply as a
variant form of the mitotic...

Sequencing of its
genome showed that the
evolution of
avocados was
shaped by
polyploidy events and that
commercial varieties have a
