|MadSci Network: Genetics|
Dear Letty, Your curiousity does you proud, but other organisms should also be considered when considering chromosomes. Believe it or not, a hermit crab has a grand total of 254 chromosomes (127 pairs), but some ferns such as Ophioglossum can apparently beat this record with 768 - outside your realm of the animal kingdom. On the other hand, minimum number games are won by the animal kingdom's Ascaris (a roundworm) with 2 (one pair) against the two pairs owned by a little daisy(4 chromosomes) Perhaps these simplistic answers will guide you to a lifelong and life-loving interest in the respective creatures and other life-forms that you pick from this intriguing list. Even mathematicians would now turn to the study of why in tarnation do these things have so many or so little. On a more everyday level, perhaps yopu might be interested to have a reminder that the humble and ever-so-useful fruitfly has 4 pairs of very-well- mapped chromosomes. Very old and therefore easily found ref.( in the US.)--- EJ. Gardiner,1960 Principles of Genetics, pp.150-152.
