Dina Asher-Smith will go for the 100m and 200m sprint double after Great Britain confirmed its squad for the 2019 World Championships in Doha.
Laura Muir will focus on the 1500m rather than add the 5,000m to her schedule at the event, which takes place from 27 September to 6 October.
Adam Gemili and Zharnel Hughes will both contest the men's 100m and 200m sprint double.
Heptathlete Katarina Johnson-Thompson is also in the 72-strong GB squad.
Kyle Langford, who was recently fined after an incident where he appeared to grab a race official by the throat, has also been picked in the 800m.
But sprinter CJ Ujah has pulled out with a back injury and has been replaced in the relay squad by Harry Aikines-Aryeetey.
"Given the standard of performances from British athletes this season, and the strength in depth we possess in several events, finalising the team was far from easy and there were some tough decisions to make," said British Athletics performance director Neil Black.
"In the 72 athletes, I truly believe we have selected the strongest team possible to compete for medals on the global stage.
"The team is full of world-class athletes who over the past two years since we were hosts in London have proven that they belong on the global stage.
"We have selected more women than men once again for a major championships."
Black also said a "special mention" needed to go to Martyn Rooney, who has been picked in the 4x400m relay squad and will be taking part in his eighth World Championships.

Dina Asher-Smith and Katarina Johnson-Thompson are the leading medal hopes in the British team named today.
Asher-Smith underlined her medal chances last week when she finished second in the 200m at the Diamond League final in Zurich.
Johnson-Thompson is set for a gold medal showdown with the reigning champion Nafissatou Thiam in a repeat of their duel for the European gold in Berlin last year.
Laura Muir is the world's third fastest over 1500m this season but has to overcome a recent injury and the men's 4x100m relay team defend the title they won in such dramatic style two years ago in London.
