I am pregnant and had a big nose before I got a nose job done. will my child have a big nose??

The short answer is maybe your child will have your nose and maybe they wont. Heredity is the study of how genes are passed from one generation to the next and it is a fascinating field to learn about. What it would say about your child's nose is that the child's nose might look like yours, it might look their father's, or it might look like the nose of an ancestor somewhere up the family tree. The reason for this is that every person has two full sets of genes for every feature we have. Because we have only one body, a lot of these genes go unused and might get passed on to the next generation. So the answer to your question is maybe and maybe not. Either way, congratulations on your upcoming child.
