- The link between SCT and increased risk of death has been documented. Is that not enough to warrant testing, as long as a link exists? Couldn't one argue that it would instead be neglectful to NOT test for this trait since we do know that such a link exists?Why are monozygotic twins who are reared apart so useful in the calculation of heritability? What assumption is being made about their respective environment?What does “prezygotic” mean?
