What is the function of the fused kinetochore found on sister chromatids in prometaphase i?

The correct answer will be- it helps in reductional division during meiosis I.

Explanation:

The kinetochores are the disc-shaped proteins formed on the chromatids which attach the spindle microtubules.

During prometaphase, I, the kinetochores forms fused structure which helps in the segregation of the sister chromatids to the opposite poles and helps in reducing the ploidy from diploid to haploid. This reduction takes place at the anaphase I of meiosis I.

Thus, it helps in the reductional division during meiosis I am the correct answer.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

well the answer is 2!
