Adam Gemili has missed out on an individual place in the Great Britain squad for the World Championships in London, which start on 4 August.
Zharnel Hughes was preferred in the 200m after Gemili came sixth in the British trials but the 23-year-old is included in the 4x100m relay squad.
Double world champion Mo Farah will defend his 5,000m and 10,000m titles.
Scotland's Laura Muir, who holds five British records, will go for the double in the 1500m and 5,000m.
Katarina Johnson-Thompson will compete in both the heptathlon and the high jump.
Reigning long jump world champion Greg Rutherford is also named in the squad despite an ankle injury.
The 30-year-old said he is "doing everything" to give himself the best chance of success at the World Championships, which is live across the BBC.

"This feels bigger for us than Rio," said Neil Black, the performance director for British Athletics.
"We've selected some incredibly talented athletes, and in many events there have been some close calls.
"It's now up to them to grasp this opportunity and produce performances that will make the whole nation proud."
Dina Asher-Smith has earned an individual place in the women's 200m and the women's 4x100m relay despite only returning to action last month after breaking a bone in her foot.
Rio Olympic bronze medallist Sophie Hitchon will compete in the hammer, while European indoor hurdle champion Andrew Pozzi will compete in the men's 110m hurdles.
Perri Shakes-Drayton, who last represented Britain at the 2013 World Championships where she sustained a knee injury which has kept her out of international competition ever since, makes her return in the 4x400m relay.
There will be a second and final selection meeting on the 24 July, where athletes who have achieved qualifying standards can be added to any unfilled places.
'Expectations will have to be managed'- analysis
BBC Radio 5 live athletics correspondent Mike Costello:
Of those missing out, Adam Gemili and Christine Ohuruogu have both been struggling for different reasons this season. Gemili has been affected by injury and Ohuruogu has been lacking in motivation this season.
At 33, it would seem that the former world and Olympic 400m champion's championship career appears to be coming to an end.
In terms of the medal prospects, the leading hope for Great Britain will be Mo Farah.
Britain won seven medals at the 2016 Olympics in Rio and at the most recent World Championships in Beijing in 2015.
This is very much a transitional period for British Athletics and their expectations will have to be managed.
They might struggle to reach the total of seven medals but they will be buoyed by home advantage in London.
