Giuseppe Sculli struck in the first half and Diego Milito converted a stoppage-time penalty to leave Milan with no points in Serie A after they lost their opener 2-1 to promoted Bologna.
The result on Sunday increases the pressure on coach Carlo Ancelotti following Milan's disappointing fifth-place finish last season and an embarrassing 2-0 defeat at second-division Swiss side Lugano in a friendly on Wednesday.
Champions Inter Milan beat Catania 2-1 at home and last year's runners-up AS Roma lost 3-1 at Palermo on Saturday.
No joy for Ancelotti
"Looking at the standings there's nothing to be happy about," Ancelotti told Sky television.
"But we have what it takes and the time to put things right and I'm sure we will. The club is supporting me and my relationship with the players hasn't changed."
Milan, fielding an attacking trio of Ballon d'Or winners Kaka, Andriy Shevchenko and Ronaldinho, made the early running, but Sculli fired the home side in front on the half hour.
Genoa continued to pose a threat and Milan keeper Christian Abbiati produced good saves to stop Sculli and Anthony Vanden Borre doubling their side's lead.
Substitute Alexandre Pato blasted Milan's best chance of the second half at Genoa keeper Rubinho.
Argentine Milito wrapped things up with a spot kick after being tripped by Paolo Maldini.
Naboli hit back
Napoli came from behind to beat Fiorentina 2-1 thanks to second-half goals by Marek Hamsik and Christian Maggio after Adrian Mutu had put the visitors ahead.
The end stands of Napoli's San Paolo stadium were closed and will remain shut for the next two home games as a penalty after violence marred their opening-day visit to Roma.
The game was also one of three games considered high risk which away fans were banned from, along with Genoa-Milan and Saturday's match between Inter and Catania at the San Siro.
Lazio are the early pacemakers courtesy of a 2-0 home win over Sampdoria secured with goals by Mauro Zarate and Goran Pandev.
Atalanta also have a 100 per cent record from two games after Tiberio Guarente gave them a 1-0 victory at Bologna, while Juventus beat Udinese 1-0 in Turin courtesy of a 67th-minute Amauri strike.
Nicola Amoruso scored as Torino drew 1-1 at his former club Reggina, while Siena beat Cagliari 2-0 and Lecce beat Chievo Verona by the same score.
