Researchers from the Universities of Oxford, Stockholm and Linkoping have studied red junglefowl – that's a chicken, not a woman – and found that mating with different males makes offspring more resistant to disease.
Similarly, men who have been imprisoned and paroled will have a harder time supervising their children, Mr. Sabol said, making their offspring more likely to get into trouble.
To me, [what is] more interesting is that when an abalone makes offspring, it makes millions and millions of offspring that have the genetic information to build a beautiful shell.
Theory about sex ratio predicts that to minimize the variance in offspring number, hermaphroditic females should make more offspring of the sex that is less variable in survival (Proulx 2000, 2004).
MC1 mainly achieved these high genetic responses by avoiding extreme relationships among the offspring, i.e. fullsib offspring are avoided, and by making the contributions of ancestors to offspring more equal by mating least related animals.
We know that we can impact our DNA for sure, and it would be useful to do that to say, make more resilient offspring.
Meanwhile, Vince Vaughn's bullish charisma makes Delivery Man (Entertainment One, 12), in which a deadbeat sperm-bank supplier fights to protect his identity from 142 of his biological offspring, more raucous and affecting than it probably deserves to be.
Mammalian females go for quality offspring, more than quantity.
They then made a special mosquito with a gene that could break up that fluorescence and engineered it so that its genes would pass on to its offspring more aggressively than those of its mate.
They also mate for life, and produce relatively few offspring, making it more difficult for them to recover from a cataclysmic event.
