Which of these descriptions of the behavior of chromosomes during meiosis explains mendel's law of segregation?

Hello, I noticed that this question was missing its options, so I went online to find them. Here they are:

Which of these descriptions of the behavior of chromosomes during meiosis explains Mendel's law of segregation?

A. The two alleles for each gene separate as homologous chromosomes move apart during anaphase I.

B. The arrangement of each pair of homologous chromosomes on the metaphase plate during metaphase I is random with respect to the arrangements of other pairs.

C. Sister chromatids separate during anaphase II.

The correct answer is: A) The two alleles for each gene separate as homologous chromosomes move apart during anaphase I.

Explanation:

Gregor Mendel, considered the father of genetics, studied the process of inheritance by experimenting with pea plants. After seeing the results, he established that each gamete -as a result of meiosis- will receive just one gene copy that is selected randomly. This is what is called Mendel's law of Segregation.

Out of all of the options given, the correct one is option A. Though all of the options describe different events that occur in Meiosis (the cell division process that generates gametes), the only one that explains Mendel's Law of Segregation is option A, because is the option that describes the separation of the two alleles of the gene.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
