Creating multiple embryos in the lab then screening them for diseases etc. can of course help with some situations, but if both chromosomes from one parent carry some variant of a gene, you can't get rid of it. Similarly, you can't introduce desired variants if none of the two parents want them. So arbitrary edits are way more powerful.
- s1artibartfast 6y agoI think powerful is a loaded word, but the rest of what you said is correct. They are different technologies for different things. Crispr is "good" for single genes. Screening is "good" for polygenic traits. For example, intelligence is thought to be linked to over 500 genes. This would not be good target for embryonic editing, even if the error rate was extremely low.
