Answer:
Even where children's genes look identical to their parents, their bodies and minds could well differ, influenced by many other factors, including the portions of the parents' DNA that don't code for genes, their environment, and their behavior.
Explanation:
Answer:
Children never look exactly like one parent because they are not clones of either parent. You get one copy of every gene from each parent, these copies are called alleles. Your physical appearance is determined by the interplay between the products of these alleles. For simple characteristics (those determined by only one gene) sometimes the allele from one parent produces a characteristic (we call this a phenotype) that is dominant to the characteristic produced by the other parent's allele. In this case, the child will have the same characteristic as one parent. However, in most cases, visible characteristics are determined by the interplay between products of dozens or even hundreds of genes. Layer on top of that the effects of the environment (aka even the exact same allele combination will produce different phenotypes in different environments).
This is why even when children look similar to one parent in certain aspects they are not identical. For example, you and your child may both have green eyes but when you look closely the iris patterns are not identical and the color is slightly different.
In equation format
characteristic = alleles from parent 1 + alleles from parent 2 + environment
