Unit 6: Patterns of Inheritance.
"It is from the progeny of this parent cell that we all take our looks;
we still share genes around, and the resemblance of the enzymes of grasses
to those of whales is in fact a family resemblance." - Lewis Thomas, American
physician and author of The Lives of a Cell.
"Scientists announced that they have located the gene for alcoholism.
Scientists say they found it at a party, talking way too loudly." - Conan
O'Brien.

imprinting in humans (16b)
- Silent Struggle: A New Theory of Pregnancy - New research on genomic
imprinting and its evolution (optional)
- "The most striking case of large-scale genome imprinting involves
crosses between horses and donkeys. Cross a female horse and a male donkey
and you
get a mule. Cross a male horse and a female donkey and you get a hinny,
altogether a different creature. Clearly, the same genes act out different
roles, depending
on whether they come from mom or dad."
- The
Maternal Grandsire Effect: Secretariat, perhaps the greatest thoroughbred
of all time was not matched by his direct offspring,
who by and large were unremarkable. His greatness was passed on through
his daughters, many of whom went on to produce great performers. (optional)
- Genomic imprinting (optional)
- Genome
biology: She moves in mysterious ways - The human X chromosome is
a study in contradictions. The detailed sequence of the X, and a survey of
inactivated genes in females, help to illuminate
this unique 'evolutionary space'.
