Question

Explain where a person's DNA comes from.

Answer 1

Your DNA resulted from 2 hapliod (has 1/2 the number of DNA) cells. A sperm from your dad and an ovum from your mom.

In haploid cells, copies of their original DNA are made, but a process called "crossing-over" scrambles this DNA so that the offspring aren't exact half cut and past of the parents.

One reason why sexual reproduction has genetic variation.

Hope this helps!

Answer 2

Answer: Parents.

Explanation: The DNA can be defined as the genetic material that is transferred from the parents to the organism.

Half of the chromosomes are transferred from the father and the rest half is transferred from the mother.

The crossing over of the chromosomes (father and mother) provides variation and the child looks has a combination of characters from both the parents but are not exact copies of parents.

So, the conclusion is a person gets its DNA from parents.
