Explain why offspring may or may not resemble either parent

The offspring can have some features for the parents relatives and can look nothing like the parents. They can look exactly alike to more of one parent then the other or have features from both parents as well
Hope this helps :3

 as we have seen family's when mom looks very much like the children this is when the dominant genes were more connecting at birth. Another reason an offspring may look more like the mother than the father because she had the dominamt genes, and the father the recessive genes, dominant being coviring the recessive.
