Strawberry plants can be grown from seeds produced through sexual reproduction. They can also be grown from runners, which are produced by asexual reproduction.
State one reason why commercial strawberry growers prefer to grow plants from runners (asexual reproduction) rather than seeds.
A particular virus infects strawberry plants, causing a reduction in fruit yield. In a major growing region, 1.6 × 108 strawberry plants are grown annually across 8,000 8,000\,8,000 hectares of land. It is estimated that 2.4% of all these strawberry plants are infected with the virus.
