A maternal diet that contained a high (versus low) amount of omega 6 fatty acids increased the risk for mammary gland cancer in the carcinogen treated offspring [ 4].
The shifts in mutation level that have been observed are sufficiently large to cause disease recurrence even within a single generation after producing effectively treated offspring.
Had the same number of controls and treated offspring been used in the original study, power would have decreased from 0.83 to 0.34, with the likely consequence that Sharpe et al. (1995) would have overlooked the reported OP effects altogether.
This term does not appear in Price's theorem because that equation treats offspring phenotype and fitness as parameters, rather than random variables (i.e. each individual has a specific value of ϕ o and of fitness, rather than a distribution of possible values for each of these).
Many parents — who have shed their status as old fogy untouchables and become pals with their progeny — are treating their offspring as worldly equals.
We have 80% power with a 5% two-sided significance level to detect a 1.97 increase in odds of IQ < 85 in untreated SGTF offspring assuming treated SGTF offspring have a mean IQ of 100 with a SD of 15.
Treating the offspring from open-pollinated families as half-sibs is often associated with inflated heritability estimates, resulting in an exaggeration of the expected genetic gain [ 33- 35].
The mean size of the litters of treated (12.3 offspring per litter) and control (10.6 offspring per litter) were similar.
Logistic regression will be used to identify if untreated SGTF offspring have increased odds of an FSIQ < 85 compared to treated SGTF offspring.
He scoffs at Mr. Ariès's notion that medieval parents treated their offspring like little adults.
