Species have similar characteristics, but they are rarely, if not never, identical; the difference between them is variation!
Hope this helps! :)
Answer:
39 double helical DNA molecules.
Explanation:
- Meiosis always produces haploid cells.
- Sperm and Eggs are produced after meiosis.
- So, sperm and egg cells of dog would have 39 chromosomes and one double helix DNA molecule is present in each chromosome comprising 39 double helical DNA molecules.
<em>A chromosome has one DNA molecule before replication and have two DNA molecules after DNA replication.</em>

The structure that surrounds the cell membrane of some cells, giving the cell a rigid shape is the cell wall.
Meiosis a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
