Susceptibility to disease means that a person is likely to fall ill, if they are in contact with germs.
Many diseases kill people, so those that are more susceptible to diseases are more likely to die before their reproductive age. Some diseases make people infertile; so in short - susceptibility to disease means that people are less likely to reproduce and spread their genes, so the entire population will be less susceptible to these diseases in the future - and this process is called natural selection!

Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
