Answer:
they considered valid but a certain idea of acquired characteristics being inherited was rejected
Explanation:
his theory was that if the environment demanded a need or use of a structure in an organism it developed it in response to demand leading to natural use or disuse of structures which he said that these new structures would be passed to their offspring leading to emergence of a new species. scientists accepted that the environment has a role in directing phenotypic changes in an individual taking a body builder for example since his muscles will become huge due to continuous use of the muscles in exercises
but scientists rejected his theory of these acquired characteristics were inherited since phenotypically acquired characteristics that do not affect the genotype of an individual can't be inherited

Answer:
The correct answer to fill in the blank is: transformation.
Explanation:
Transformation is a process that happens to a) cells when they change their phenotypes due to new genetic material, or b) cultured cells that keep having spontaneous phenotypic alterations due to the changes in their DNA.
Transformation can occur because spontaneously, or because of an infection with a transforming virus, gene transfection, exposure to chemical carcinogens or exposure to ionizing radiations.
Answer:
The most appropriate answer would be option 2.
In humans, the color of the eyes was thought as a simple Mendelian trait however, it has been found that the color of the eye follows polygenic inheritance, that is, it is determined by multiple genes.
A set of 15 genes is responsible for the color of the eyes. Two genes out of these 15 are OCA2 and HERC2 which are present on chromosome 15.
Thus we can conclude that eye colour is polygenic trait which does not follow Mendelian genetics.
