Which Diagram Represents Prophase I Of Meiosis

E independent assortment of chromosomes occurs. Previous question next question.

Control Of Oocyte Meiotic Maturation And Fertilization

B the process is preceded by replication of the dna.

Which diagram represents prophase i of meiosis. A prophase i answer. The diploid nucleus enlarges in volume. Three months after conception the ovaries contain two million oocytes arrested in prophase i.

So if the question asks which diagram represents prophase 1 and which one shows chiasmata then youre rightdiagram iv does show chromosomes crossing over however this takes place during prophase 1. 32 crossing over occurs during which phase of meiosis. Crossing over in meiosis happens during a subphase of prophase 1 called pachytene.

Get more help from chegg. During this phase of meiosis the nuclear envelope shown in white in the diagram at right breaks up and disappears. I iii iv v.

Which diagram represents chromosomes in prophase i of meiosis. The important features of all these five sub stages are under mentioned. B centromeres uncouple and chromatids are separated from each other.

The random nature of the fertilization of ova by sperm. The random distribution of the sister chromatids to the two daughter cells during anaphase ii. Well the chiasmata are points of crossing over.

Also the spindle apparatus yellow strands in the diagram. D the following questions refer to the essential steps in meiosis described below. The random and independent way in which each pair of homologous chromosomes line up at the metaphase plate during meiosis i.

Iv a cell divides to produce two daughter cells that are genetically identical. I ii iii iv v vi which diagram represents anaphase ii of meiosis. This problem has been solved.

The nucleolus also vanishes. This can be interpreted that the development of an egg is stalled in meiosis division until ovulation and fertilization. This is a complicated and prolonged phase of meiosis which can be subdivided further into five sub stages ie leptotene zygotene pachytene diplotene and diakinesis.

Spermatogenesis begins at puberty but 300 500 million are made per day. A refer to the drawings in figure 132 of a single pair of homologous chromosomes as they might appear during various stages of either mitosis or meiosis and answer the following questions. The chromosomes shown in red become visible as they shorten coil and thicken that is as they condense.

Figure 132 which diagram represents prophase i of. Which drawing represents a stage of meiosis in which independent assortment might occur if there were more than one pair of chromosomes represented. The key statement is.

Figure 132 33 which diagram represents prophase i of meiosis.
