I iii iv v.

Which diagram represents prophase i of meiosis. I ii iii iv v vi which diagram represents anaphase ii of meiosis. 32 crossing over occurs during which phase of meiosis. 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.

Well the chiasmata are points of crossing over. The random nature of the fertilization of ova by sperm. This can be interpreted that the development of an egg is stalled in meiosis division until ovulation and fertilization.

Also the spindle apparatus yellow strands in the diagram. Crossing over in meiosis happens during a subphase of prophase 1 called pachytene. The nucleolus also vanishes.

D the following questions refer to the essential steps in meiosis described below. This problem has been solved. 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.

B centromeres uncouple and chromatids are separated from each other. Spermatogenesis begins at puberty but 300 500 million are made per day. Get more help from chegg.

B the process is preceded by replication of the dna. The random and independent way in which each pair of homologous chromosomes line up at the metaphase plate during meiosis 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.

The key statement is. The chromosomes shown in red become visible as they shorten coil and thicken that is as they condense. The important features of all these five sub stages are under mentioned.

Iv a cell divides to produce two daughter cells that are genetically identical. Which drawing represents a stage of meiosis in which independent assortment might occur if there were more than one pair of chromosomes represented. E independent assortment of chromosomes occurs.

A prophase i answer. During this phase of meiosis the nuclear envelope shown in white in the diagram at right breaks up and disappears. The random distribution of the sister chromatids to the two daughter cells during anaphase ii.

Previous question next question. Figure 132 which diagram represents prophase i of. Three months after conception the ovaries contain two million oocytes arrested in prophase i.

Which diagram represents chromosomes in prophase i of meiosis.
