A hallucination of movement, or a feeling of spinning or dizziness, is called: VERTIGO.
It can be due to the inner ear or the brain.
Tetraploidy may result from
(c)lack of cytokinesis in mitosis and
(d) nondisjunction in mitosis in the early embryo.
<h3>What exactly are tetraploidy and triploidy? Tetraploids are they fertile?</h3>
Triploidy happens quite frequently, whereas tetraploidy is an uncommon chromosomal anomaly. In the first trimester, the majority of triploid embryos miscarry. The conceptus has a triploid karyotype in about 20% of first-trimester spontaneous abortions, according to the research. Chromosome duplication in a somatic cell of an early cleavage-stage embryo, a postzygotic event, is the most likely cause of tetraploidy. A rare diploid ovum may be fertilised by a similarly rare unreduced sperm.
Although the tetraploid form on the left is self-fertile, crosses with the parent diploid form result in sterility. It might then be broadly regarded as a new species, or at the very least the building blocks for the eventual emergence of a new species.

An observation is something you notice about what you're reading/looking at, while an inference is something you put together based on information you've gathered.
