Chromosomes aren't visible yet. Chromosomes become evident.

2) Prophase centrioles shift from one side of the cell to the other. Each homologous pair of chromosomes joins to generate a bivalent chromosome.

3) Late Prophase - In a bivalent, each chromosome divides into two chromatids. There is genetic mixing. Crossover points (Chiasmata) become evident. The bivalents align themselves on the spindle's equator during metaphase.

4) Anaphase - Each homologous chromosome's chromatid pairs split apart and travel to opposing poles of the cell.

5) Telophase - Cytokinesis commences, resulting in the formation of two new cells, each with two copies of each chromosome.

6) Prophase 2: A new spindle develops at an angle to the previous one. 

7) Metaphase 2 - Chromosomes, each of which is made up of two chromatids, align on the spindle's equator. 

8) Anaphase 2 Chromatids are forced apart to produce two chromosomes, which subsequently migrate to opposing poles of the cell during anaphase 2.

9) Cytokinesis begins in Telophase 2. Four haploid cells have been produced, each with only one chromosome. Each chromosome has its own genetic makeup.]]> 2022-04-04 01:06:53 UTC https://padlet.com/josephgreen12/mmaowirqne9c7zbl/wish/2127698712 josephgreen12 https://padlet.com/josephgreen12/mmaowirqne9c7zbl/wish/2127706315 1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibers by their centromeres
2) Metaphase: chromosomes line up along the metaphase plate (center of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin ]]> 2022-04-04 01:12:57 UTC https://padlet.com/josephgreen12/mmaowirqne9c7zbl/wish/2127706315 Fowler, S., Roush, R. & Wise, J.

Gregor Mendel discovered the independent arrangement of genes and their related properties in pea plants in 1865 while studying genetics. Mendel was doing dihybrid crosses, which are crosses between organisms with two characteristics that vary. He noticed that the combinations of qualities in the progeny of his crossings didn't always match the parental organisms' combinations of attributes. He developed the Principle of Independent Assortment based on these findings."- Nature josephgreen12 https://padlet.com/josephgreen12/mmaowirqne9c7zbl/wish/2127745051 2022-04-04 01:43:59 UTC https://padlet.com/josephgreen12/mmaowirqne9c7zbl/wish/2127745051 Mendels Law of Assortment josephgreen12 https://padlet.com/josephgreen12/mmaowirqne9c7zbl/wish/2127752199 The behavior of the chromosomes proves Mendels theory that 2 different parent genes are assorted into gamates that are seperate of each other. The allele that a gamate reciveces for a gene does not influence another allele with a different Gene. ]]> 2022-04-04 01:48:37 UTC https://padlet.com/josephgreen12/mmaowirqne9c7zbl/wish/2127752199
