A species of microscopic organism can reproduce both asexually and sexually.
Scientists started populations P and R with the same number of organisms and the same amount of genetic variation.
The table shows the number of new organisms produced in 24 hours.
| Population | New organisms produced asexually | New organisms produced sexually |
|---|---|---|
| P | 480 | 0 |
| R | 210 | 90 |
The scientists then took equal numbers of organisms from populations P and R and exposed them to a new disease.
Explain why population P produced more new organisms than population R in 24 hours.
Explain why the sample from population R is more likely than the sample from population P to contain organisms that survive the disease.
Use the data in the table.
