  • n. the condition of being polyploid

Etymologies

From polyploid +‎ -y, after German Polyploidie. (Wiktionary)

Examples

  • Although the cell's chromosome-containing nuclei divided normally, the cells themselves didn't divide, resulting in too many nuclei per cell-a condition known as polyploidy that's exhibited by many cancer cells.

  • In other words, macrogenetic changes might occur suddenly (e.g. polyploidy leading to speciation in plants), but that changes to the overall structure of the organism, changes that require coordinated changes, occurs through evolution by natural selection.

  • The inferred chromosome numbers of these extinct species suggest that seven to nine is the primitive haploid chromosome number of angiosperms and that most angiosperms approximately 70 percent have polyploidy in their history.

  • Abstract: Three published estimates of the frequency of polyploidy in angiosperms 30 to 35 percent, 47 percent, and 70 to 80 percent were tested by estimating the genome size of extinct woody angiosperms with the use of fossil guard cell size as a proxy for cellular DNA content.

  • He was lucky to have chosen traits in his plants that are governed by such genotypic interactions by luck; if he'd observed phenotypes influenced by polyploidy he would probably have concluded that 'god did it.'

  • Furthermore, high levels of polyploidy in many arctic vascular plant species may promote the proportion of the genetic variation partitioned within individuals, which may be important when passing through evolutionary bottlenecks [6].

  • My proposal regarding the human body and design isomorphism is entirely detachable from the C-value enigma, polyploidy, etc.

    A Dubious "Opportunity" for IDers

  • You are saying that mutations suddenly appear when an opportunity is opened that allow them to become adaptive, and that the processed pseudogenizations, tandem repeats and polyploidy events are all "good stuff waiting to happen".

    A Dubious "Opportunity" for IDers

  • The incidence of polyploidy remained below 0.5%, however, nor did it rise with higher radiation doses.

  • I remember this one from Biology class. Genetics is full of interesting words.

  • I did Wiki the thing! But it still sounds like the fakest word I've ever heard. I mean, it's marvellous, don't get me wrong.

    P.S. I like the spelling "marvellous" better than "marvelous." Just like murther is better than murder.

  • Absolutely real. From a biology text I'm editing. "The condition of some biological cells and organisms manifested by the presence of more than two homologous sets of chromosomes." Go on, Wiki the thing.

    Isn't it wordtacular?

  • This word can't be real. It sounds like a children's book character, or a name you shout at someone on a playground!
