Why do we not look exactly like our parents or siblings, even though we inherit genes from our parents?

That is one of the greatest reason that we have things most common in with our grandparents

Children often look like some combination of their parents. This is because each parent gives the child some of themselves {gene}. A child is made from the information found in the cells of the parents.These characteristics are called genes.
The traits that you can observe in a person are called that person's phenotype.For example if we see a boy or a girl when they are born that is what their phenotypes are. The information that makes a person look the way they do is encoded in structures called chromosomesthat are found in their cells. The specific genes found on these chromosomes make up what is called that person's genotype. Genotypes are what genes does a baby has like if its a boy that boy genotypes are X,Y and if its a girl it is X,X. X,X and X,Y are the main genes or genotypes.
In humans, each person has two copies of each type of chromosome. That means they have two copies of each gene, but a person will give only one of these genes to their child. For example, a person could have a gene for brown hair and a gene for blond hair. He would give one of those traits to his child. The child's phenotype would depend on what gene he received from his other parent.
So children look like combinations of their parents because they are. Each parent gives half of their genetic material to their children. The combination makes a unique combination of their parents genes.
The scientific study of how traits are passed from parents to children is called genetics.
Chromosomes in the nucleus of the cell contain information of inheritance of features from parents to next generation in the form of DNA (Deoxyribo Nucleic Acid) molecules
