| 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.)---
