生まれたのも 育ったのも 京都なんですよ is formed when you combine two sentences, "I was born in Kyoto" and "I also grew up in Kyoto." Another example is ミュジカルで 歌ったのも 踊ったのも 初めてなんですよ when you combine two sentences "I sang in the musical for the first time" and "I also danced in the musical for the first time." When you combine two or more sentences together, you add のも to the verbs (past casual tense: 生まれた、育った、歌った、踊った etc.); however, you add も to nouns as in 宿題(homework)も 教科書(textbook)も 忘れた when you combine two sentences "I forgot (to bring) my homework" and "I also forgot (to bring) my textbook."
I hope this helps.
