Is it possible for descendents of the same ancestral gene to
have different numbers and postions of their introns in different
species of organisms ?
I have cloned a gene (from a protozoa) which is
homologous to all members of a particular family of
protein kinase. Most members of this family documented in databases are
from plants. These genes displayed 10 introns where genomic sequences are
available and the positions of their introns are conserved.
Assuming my gene originated from the same ancestral gene as those with
10 introns, what is the explaination for the observed differences?
