Arabidopsis is popular as a model because it undergoes the same processes of growth, development, flowering, and reproduction as higher plants, yet its genome has about 30 times less DNA than a corn or human genome and very little repetitive DNA.

Arabidopsis has 10,000 or so more genes than the fruit fly-Arabidopsis has almost as many genes as a human.

Arabidopsis thaliana
: A small member of the mustard family (kitchen cress). It has a very small genome (130-140
Mbp
), five chromosomes and contains almost no repetitive DNA. Its genome will be completely sequenced by the end of 2000.

One important exception to the rules of segregation has been documented in the progeny (F2) of Arabidopsis thaliana plants homozygous for recessive alleles of the HTH gene (ref).
