A botanical garden produces two batches of offspring from the same species of flowering plant.
| Batch | Record of how the offspring formed | Number of different combinations of alleles found among 24 offspring |
|---|---|---|
| L | New plants developed as cells from one parent divided by mitosis. | 1 |
| M | The nucleus of a male gamete carried in pollen fused with the nucleus of an egg cell in an ovule. | 21 |
Name the method of reproduction used to produce each batch.
A new disease may reach the botanical garden. Explain why offspring in batch M are more likely than offspring in batch L to survive this disease.
