Identical twins are split from the same egg but then hormones take over. Everything thing about the body is chemical and the rate of release. While in the womb both will have different rates of growth. There’s no guarantee their all features will be the same. One twin could easily be taller later in life.

A very interesting question

Yes. Breast size can depend on weight, whether one twin wears a bra all the time, and can also be augmented by plastic surgery.

Of course. Most twins are fraternal anyhow.

It’s an issue for you? :)

Yes. Behavior influences genes. If one exercises more than the other, the muscles will get stronger including those which support breast tissue. If one takes birth control hormones and the other doesn't, more likely to have bigger breasts. If one twin weighs more, again, the same outcome.

yes ofc

🤔 Good question

Idk but big boobs skipped me and went to my little sister 😔

Why do you want to know about other's boobies? Mind your own boobies.
