A population of plants contains individuals with inherited differences in frost tolerance. In a period with no frost, the mean number of seeds produced by each type of plant was recorded.
| Plant type | Mean number of seeds per plant |
|---|---|
| More frost-tolerant | 18 |
| Less frost-tolerant | 30 |
Predict how the frequency of alleles for greater frost tolerance is likely to change over many generations if frost continues to be absent. Explain your answer using the data.
