I heard that acquired traits are inherited. That is, if a girl enlarged her breasts, then her daughter will have a big bust?

Acquired traits are not inherited, because they are not fixed in the genotype. It is simply a change in a specific organism under the influence of certain factors. Therefore, even the natural growth of the breast, stimulated, relatively speaking, by nutrition, procedures, oils, physical education and others, will not be passed on to the daughter. Surgical intervention all the more.

Acquired traits are not inherited. This is Lamarck's long-discarded theory of evolution. Neo-Darwinism now dominates. ///////

No. The woman's breasts did not increase on their own, due to epigenetic, hormonal modifications of the body, but due to external intervention, this was not the work of the body itself, recorded on the gene site. This is not considered an acquired trait, it is considered a "cosmetic repair" that does not remain in the DNA "memory". An acquired trait is that modification that manifests itself in an organism as a variation of the phenotype (that is, changes under the influence of both genes and the environment), for example. In fact, the woman's breasts remained as they were originally, the body does not respond to the implant at the genetic level, so the daughter will not suddenly have a large breast simply because her mother inserted an implant for herself. It's like saying that if a mother is a brunette and dyes her hair blonde, her daughter will be born blonde.
