What can we observe in order to visualize mendel's law of segregation? (multiple choice)? a. homologous chromosomes separating during meiosis ii b. the behavior of sex-linked genes c. sister chromatids separating during mitosis d. the replication of dna e) homologous chromosomes separating during meiosis i

Answers

What we can observe in order to visualize Mendel's Law of Segregation is homologous chromosomes separating during meiosis I. The correct answer is E.

Since the sentences are already descriptive enough, here are the proper names according to the abilities condensins and cohesins have or not:

1) generally dimeric, forming a V-shaped complex : condensin

2) hold sister chromatids together after replication, until chromatid separation : cohesin

3) each terminus contains part of a site for ATP hydrolysis : both

4) contain two coiled-coil motifs connected by a hinge domain : both

5) associated with kleisin : condensin

6) essential for DNA replication and cell division : both

7) contributes to the compaction of chromosomes during mitosis and enables proper chromatid separation during anaphase: cohesin

a. sister chromatids separate during anaphase.

Explanation:

Meiosis II is similar to mitosis because in both the divisions, the chromatids separate during anaphase of the respective cell didvisions by splitting of centromere resulting movement of chromatids towards their respective poles in the cell. Both these divisions separate into two daughter cells with the same chromosome number as in the parent cell.  Therefore, Meiosis II and mitosis are the equational division as after division chromosome number remains the same as in the parent.

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

ANAPHASE II

Explanation:

DNA condenses into chromosomes during prophase, chromosomes line up during metaphase and separate during anaphase, and separate nuclei form during telophase.

metaphase

Explanation:

Metaphase leads to anaphase, during which each chromosome's sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin — which linked the sister chromatids together during prophase — causes this separation to occur.

Sister chromatids separate during anaphase:  Mitosis, Meiosis II

Homologous chromosomes pair up and align at the metaphase plate: Meiosis I

Explanation:

After the S phase, each chromosome has two sister chromatids held together at the centromere. Splitting of centromere during anaphase of mitosis and anaphase-II of meiosis II is followed by separation of sister chromatids and their segregation towards the opposite poles of the cell.

Meiosis I is different from mitosis and meiosis II as it has many unique events that do not occur in the latter two. Prophase-I of meiosis I have many sub-stages. Zygotene of prophase I include the pairing of the homologous chromosomes to allow crossing over during pachytene. The paired homologous chromosomes align themselves at the cell's equator during metaphase I of meiosis I. This allows segregation of homologous chromosomes to the opposite poles in the subsequent stage.

The reduction division or the meiosis  in which a single cell divides into four daughter cells. The meiosis shows the reduction division as the chromosome number reduces up to half in the daughter cells.

Sister chromatid separation occurs in the anaphase of meiosis. The failure of segregation of sister chromatid at Meiosis II will result in the formation of two normal haploid daughter cells. The one daughter cell will have the one extra chromosome whereas another cell will have one less chromosome number.

they're pulled apart during Anaphase II
