If two brown-eyed parents have produced three blue-eyed sons and if they have another child, it's likely their next child will be brown-eyed. Both parents have a recessive allele for blue eyes, so it is a 75 percent chance the next will be brown-eyed.
Hope that helps. -UF aka Nadia
This case of mistaken identity called imprinting. The best-known form of imprinting is filial imprinting, in
which a young animal acquires several of its behavioral characteristics from
its parent. It is most obvious in nidifugous birds, which imprint on their
parents and then follow them around.

The Griffith's experiment, the Avery-MacLeod-McCarty experiment, and the Hershey–Chase experiments were the set of experiments that established DNA as the key hereditary molecule. The Avery-MacLeod-McCarty experiment was an extension to the Griffith's experiment. The heat killed virulent S strain cells of the Griffith's experiment were lysed to form a supernatant containing a mix of RNA, DNA, proteins and lipids from the cell. The supernatent was equally divided into 3 parts after the removal of the lipids. The 3 parts were respectively treated with an RNAase to degrade the RNA, DNAase to degrade the DNA and proteinase to degrade the proteins. The treated supernatant was then added into the culture containing the non-virulent R cells. In case of the supernatant treated with the DNAse, no transformation of R cells into S cells occurred. The transformation of R cells to S cells occurred in the proteinase and the RNAse cases. This indicated that DNA was the hereditary molecule and not protein or RNA.

Answer:
A trait that gives an organism a reproductive advantage in the current environment
Explanation:
- Adaptations are mutations that helps an organism, such as animals or plants to survive in its environment due to a reproductive advantage.
- Adaptations may be structural or behavioral adaptations. Structural adaptations are features or the physical part of an organism that boosts its survival. Behavioral adaptations on the other hand, are responses made by an organism to help it survive or reproduce.
