The
area to which I've given the greatest attention is a new
phenomenon in molecular biology called genomic imprinting,
which is a situation in which a DNA sequence can have conditional
behavior depending on whether it is maternally inherited—coming
from an egg—or paternally inherited—coming through
a sperm. The phenomenon is called imprinting because the
basic idea is that there is some imprint that is put on
the DNA in the mother's ovary or in the father's testes
which marks that DNA as being maternal or paternal, and
influences its pattern of expression—what the gene
does in the next generation in both male and female offspring.
GENOMIC IMPRINTING : A TALK WITH DAVID HAIG [10.24.02]
Introduction David
Haig is an evolutionary geneticist/theorist interested
in conflicts and conflict resolution within the genome,
with a particular interest in genomic imprinting and relations
between parents and offspring. DAVID
HAIG is Associate Professor of Biology in Harvard's Department
of Organismic and Evolutionary Biology and author of Genomic
Imprinting and Kinship.
