Meiosis is when the parent (haploid) cells divides into two to create for daughter cells having half chromosome's number. This the produce sex cells or gametes - sperm for males while eggs for females. The division is in 9 stages here there is meiosis I then there is also meiosis II.
A cross between a diploid individual and a tetraploid individual produces triploid offspring. There are many species of plants that are triploid, but those come from crosses between two triploid individuals. In those cases, the chromosomes from one parent match up with the chromosomes from the other parent just fine. The same is not true with a cross of a tetraploid and a diploid. In that case, one third of the chromosomes are unmatch, causing many offspring to die, to be sterile, or to be generally unfit. Long story short, the answer you seek is False.
