Bhakoot Dosha and Gana dosha in horoscope matching is never good. It indicates problems in marital life. Bhakoot Dosha are three types, you have not specified which bhakoot dosha you have. The effects and remedy of all three are different. Gana dosha indicates temperament problems, Gana dosha is formed when one person , mostly the Girl belongs to Rakshasa Gana. The person with Rakshasa Gana is short tempered, self centered. Bhakoot and Gana dosha is never good. Marriage should be done if Bhakoot dosha and Gana dosha get cancelled.
