here is your answer

Explanation:

1. Lamarckism consist of two theories which were proposed by Jean Baptiste lamarck.

These are follows :

a)use and disuse of organs

b) inheritance of acquired characters.

2.

• in theory of use and disuse of organs, lamarck says : the charecters of organs develop because specific activities that the organisms performed.
• if such organs is not used it gets degenerated. thus, the morphological changes taje place due to activities or laziness of a particular organisms.
• to emphasise this theory, he quoted following examples.
• due to constant extension of neck to eat foliage from the top of the trees, giraffes neck become long.
• such acquired charecters are passed from one parental generation to the offspring this is called inheritance of acquired charecters.
• the theory of inheritance of acquired charecters does not take place. only genetic charecters are transmitted.
