Question:

The genomic content of the nucleus is constant for a given species where as the extra chromosomal DNA is found to be variable among the
members of a population. Explain.

Answer:

For humans (Homo sapiens) the genomic content in the nucleus is constant i.e. 46 chromosomes but the mitochondria present in the human will have a different amount of extra chromosomal DNA.
