Difficult teenagers, the offspring most liable to vex political parents, could be conveniently removed: imagine how much easier George Bush's life would have been had his twins been confined to, say, Pyongyang.
In contrast, if less active TALEN mRNAs are used, it is more difficult to obtain offspring with the bi-allelic mutation.
This donor identified himself as gay which, he said, was not a problem to his donor 'daughter' but might be difficult for a young male offspring, should there be one; he suspected that other offspring had been born.
The horse nearly bit off the finger of the managing partner, Steve Zorn, and Gyarmati placed a large red cone in front of Adverse's stall at Belmont to warn people away, with the pride of a parent who knows her offspring is difficult but just may grow up to be somebody.
David Q's wife met him after he had been a donor; knowledge that there were donor offspring was difficult for her, especially when David Q agreed to have contact.
All members of the Oryza genus have n = 12 chromosomes and while interspecific crossing is possible within each complex, it is difficult to recover fertile offspring from crosses across complexes (Vaughan et al., 2003).
Baby boomers born between 1945 and 1965 have made the world too expensive, too difficult and dangerous for their offspring.
The effects of antenatal interventions on offspring outcome are difficult to establish.
Meanwhile, a trade-off between nutritional demands and offspring protection is difficult to study because often, predators are a threat to both adults and offspring.
This exposure misclassification could influence our effect estimates if there are differences in these factors between cases and controls for example, if mothers of case offspring had more difficult pregnancies, limiting their outdoor movement.
