In which no Diploid life is destroyed.
Unlike queens and workers, which develop from fertilized Diploid eggs, drones, or male bees, are born from unfertilized,
A regular Diploid human cell contains 46 chromosomes
and is considered 2N because it contains 23 pairs of homologous chromosomes.
If the egg is fertilised, the ant will be a female(Diploid); if not, it will become a male haploid.
An example is the chimera built off of ES cells
and tetraploid embryos, which are artificially made by electrofusion of two two-cell Diploid embryos.
These often grow faster and
produce sturdier plants that can withstand stress better than their Diploid relations(many of our crops have expanded chromosome numbers).
Some breeding programs have
made tetraploid plants by crossing triploid and Diploid varieties, but this depends on infrequent genetic events,
and so it takes time and effort.
But they can be crossed with one another to bring together useful traits,
and then with ordinary Diploid trees to make a new generation of triploid seedless bananas.
Normal Diploid cells when cultured in a petri dish in the laboratory under
appropriate conditions, grow until they cover the whole surface of the container in a monolayer.
The significance of meiosis for reproduction and inheritance, however, was described only in 1890 by German biologist August Weismann(1834-1914), who noted that two cell
divisions were necessary to transform one Diploid cell into four haploid cells if the number of chromosomes
had to be maintained.
