Sergio [31]
The 7 (sometimes 8) characteristics of life are:
1. living things are composed of cells
2. living things have different levels of organization
3. living things metabolize (i.e. use energy)
4. living things respond to their environment
5. living things grow
6. living things reproduce
7. living things adapt to their environment
(some sources include) 8. living things have genetic material

Viruses do not metabolize, they do not grow, they do not adapt to their environment, and they cannot reproduce independently; viruses require host cells to reproduce and perform the other functions that give them the appearance of aliveness.

The gene mapping refers to providing position to the genes on the chromosomes.

In the given question to construct gene map:

1. Look for the highest recombination frequency that is 50% between the C and D.

2. Now look for second-highest value and place the gene accordingly.

3.Similarly, place the genes in the decreasing order of recombination frequency and this will result that the sequence of the genes is- CABD.

Thus, Option-3 is correct.
