The correct answer is option C

During 18th century the people used to think that the planets used to move backward in the sky and this is known as the Apparent retrograde motion.

The planets of the solar system appeared to be moving in backward direction.

At that time it was not explained properly that it seems to moving backward but actually it is not. Planets move around their respective orbits only.

Sedbober [7]

Answer:

Chromosome condenses

Pairing up to form tetrad

Crossing over

Lining up on metaphase plate

Homologous chromosome separate

Explanation:

Condensation of chromosomes occurs in prophase I phase. Pairing up to form tetrad occur during prophase I. Crossing over occurs during prophase I of meiosis cell division. Chromosomes line up along the metaphase plate in the stage of Metaphase. Centromeres break down and homologous chromosomes separate in anaphase I phase of meiosis.
