Dictionary » P » Ploidy



The number of sets of chromosomes within a cell or organism. Each set is designated n so one set is n is haploid, two sets is 2n is diploid, three sets is 3n is triploid, four sets is 4n is tetraploid, etc. Also, unspecified multiple sets (but more than two) is polyploidy, and extremely large number of sets may be designated by number (for example 15-ploid for fifteen sets). The number of chromosome sets that make up the [[genome of an organism, e.g. [[polyploidy.

life cycle of buffing and fission yeast

... a morphology. It's generally assumed that any fungus can grow in that morphology under the right conditions and the morphology is not exlcusive to ploidy. We're most familiar with those fungi that exhibit the yeast mophology under routine culture conditions.

kyros: IMHO depends on how much ploidy is the plant. If is it tetraploid, the offspring would be triploid a thus should be sterile. However, if it was hexaploid, the offspring should be tetraploid and thus now problem...
