Explain why harmful mutations are mostly represented by recessive genes what would happen to the view if these mutations were in dominant genes

Harmful mutations often manifest as severe illnesses that shorten life expectancy or lead to disability. Fortunately, harmful mutations are most often represented by recessive genes. That is, for a sick child to be born, both parents must be carriers of this gene (heterozygous). At the same time, they themselves are healthy. The probability of having a sick child is 25%. If the mutation were associated with a dominant gene, then one parent, who must be sick, is enough to pass this gene to the offspring. In this case, the probability of having a sick child increases and is 50%.
