mother-->offspring

Answer 2

Answer:

Nuclear DNA :

The nuclear DNA can be inherits from the parents. The DNA is circular in shape. This DNA consists of around 20,000 genes. These are generally diploid and paired in present in the organism.

Mitochondrial DNA:

Mitochondrial DNA is also inherited but from the mother only. The DNA is linear in shape. This DNA also consists of genes but less in number as compared with nuclear DNA. These are generally haploid and non paired present in the organism.

The mitochondrial gene is used in the criminal investigation as it contains the inherited material of mother only.
