First baby born free of inherited disease

The principals are the same

I agree. The difference is that in dogs, humans wait till the dog is an adult, and then determine if it has traits they want to preserve and then breed it toward those traits. But in filtering fertilized eggs/blastocysts we'd be doing that sorting for traits that we want to preserve before the baby is even makes it to the uterus. Both are examples of selective breeding.

Marker assisted selection or marker aided selection (MAS) is a process whereby a marker (morphological, biochemical or one based on DNA/RNA variation) is used for indirect selection of a genetic determinant or determinants of a trait of interest (e.g. productivity, disease resistance, abiotic stress tolerance, and quality). This process is used in plant and animal breeding.

Marker assisted selection (MAS) is an indirect selection process where a trait of interest is selected, not based on the trait itself, but on a marker linked to it.[1][2][3][4] For example, if MAS is being used to select individuals with disease resistance, the level of disease resistance is not quantified but rather a marker allele that is linked with disease resistance is used. The assumption is that the marker used for selection associates at high frequency with the gene or quantitative trait locus (QTL) of interest, due to genetic linkage (close proximity, on the chromosome, of the marker locus and the disease resistance-determining locus). MAS can be very useful to efficiently select for traits that are difficult or expensive to measure, exhibit low heritability, and are expressed late in development. However, it is usually essential to confirm at certain points in the breeding process that the selected individuals or their progeny do in fact express the desired phenotype or trait.

Along the same lines as Eugenics....
