Hi, you've asked an incomplete question. However, I provided a brief about DNA.
Step-by-step explanation:
Indeed, human DNA contains a lot of information about who we are. The DNA in full as Deoxyribonucleic Acid contains genes and chromosomes which are responsible for the transfer of unique character traits from a parent to a child.
For example, parents who are tall may give birth to children who are also tall, or parents with green eyes may give birth to children with green eyes. Hence, Mrs. Robertson's assertions are to a reasonable extent in line with scientific findings.
