https://meddiction.com/knowledgebase/concordant-vs-discordant-twin-studies/ This resource gives a succinct explanation of what Discordance means. I think concordance is explained well in this article, I think Discordance should be addressed.

Discordance, in genetics typically means that a similar trait is not shared between twin members. Studies of twins have shown that genetic traits of monozygotic twins are fully concordant whereas in dizygotic twins, half of genetic traits are concordant, while the other half are discordant. Discordant rates that are higher than concordant rates express the influence of the environment on twin traits.
