How does diploidy help to preserve genetic variation? see concept 23.4 (page 498)?

Monoploid organisms reproduce asexually since they need to transmit all of their genetic material to their offspring. Diploid organisms, have 2 copies of their genetic material that differ slightly in their genes. Since the progeny gets half of the DNA from each parent, we have that new combinations can emerge; for example, if the mother is AA for some allele and the father aa, their offspring will be Aa, a new genotype. This might have different implications (for example, the recessive gene for thalassemia also provides resistance to malaria). Finally, during meiosis, there is also an event called crossover that increases the genetic variation of the offspring.

2. They can grow

3. They evolve to adapt to their hosts

4. They are capable of multiplication in their host cells

5. They are made up of proteins and glycoproteins like cells do

6. They have genetic information which helps them to produce more viruses in the form of either RNA or DNA.
