(1744-1829) was an important French naturalist. He was one of the first scientists to propose that species change over time. idea of the inheritance of acquired characteristics. Like him, Darwin assumed that species can change over time. The fossils he found helped convince him of that.
I. An organism recognizes the need for a change.
II. An organism will react to the recognition of the need for a change.
III. By use or disuse and organism modifies its structure to satisfy the recognition of need for a change.
IV. Characteristics acquired as a result are passed on

Explanation:

Jean Baptiste Lamarck (1744-1829) was an important French naturalist. He was one of the first scientists to propose that species change over time.

Jean Baptiste Lamarck published his theory of evolution in the book Philosophie zoologique called the theory of use and disuse or the inheritance of acquired characteristic. According to this theory, ecological conditions in which an organism lives cause it to have certain needs. These needs are met by modification of old organs or by production of new rudimentary organs.The continuous  use of the rudimentary structures allows them to increase in size and disuse causes that organ to degenerate. These changes become fix and become inheritable.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!
