Such as 5-year-old kid is given toys and books that are supposed for 7-10 years old. Or a 10-year old kid is assigned to do household chores that his older brother or sister has been doing.
Neutral mutations and Random mutations
All living things experience mutation, which has three general sorts of impacts. The first type of mutations are those that are detrimental to the fitness of their host; typically, these mutations either lower survival or fertility. The second type of mutation is called "neutral," and it has little to no impact on fitness. Because the phenotypic changes that emerge from random mutations are likely to be maladaptive, it is generally accepted that random mutations will, on average, decrease an organism's fitness.
<h3>What is Mutations?</h3>
