Paternal Effect Genes
In contrast, a paternal effect is when a phenotype results from the genotype of the father, rather than the genotype of the individual. The genes responsible for these effects are components of sperm that are involved in fertilization and early development. An example of a paternal-effect gene is the ms(3)sneaky in Drosophila. Males with a mutant allele of this gene produce sperm that are able to fertilize an egg, but the snky-inseminated eggs do not develop normally. However, females with this mutation produce eggs that undergo normal development when fertilized.

Famous quotes containing the words paternal, effect and/or genes:
“There is a great deal of self-denial and manliness in poor and middle-class houses, in town and country, that has not got into literature, and never will, but that keeps the earth sweet; that saves on superfluities, and spends on essentials; that goes rusty, and educates the boy; that sells the horse, but builds the school; works early and late, takes two looms in the factory, three looms, six looms, but pays off the mortgage on the paternal farm, and then goes back cheerfully to work again.”
—Ralph Waldo Emerson (1803–1882)
“Other countries drink to get drunk, and this is accepted by everyone; in France, drunkenness is a consequence, never an intention. A drink is felt as the spinning out of a pleasure, not as the necessary cause of an effect which is sought: wine is not only a philtre, it is also the leisurely act of drinking.”
—Roland Barthes (1915–1980)
“Whether you want it or not,
your genes have a political past,
your skin a political tone.
your eyes a political color.
...
you walk with political steps
on political ground.”
—Wislawa Szymborska (b. 1923)
