WebThe plasma membrane—the outer boundary of the cell—is the bag, and the cytoplasm is the goo. Of course, a cell is ever so much more than just a bag of goo. It's a complex, highly organized unit, the basic building block of all living things. And the plasma membrane and cytoplasm are actually pretty sophisticated. WebExplain what it means for a 9:3:3:1 ratio to be two 3:1 ratios combined at random. Use a branch diagram to illustrate this concept. A 9:3:3:1 ratio results from a self-cross of a heterozygous parent. When focusing on one gene from this parent, it will have a 3:1 ratio in the next generation (Y/y self cross will result in a 3:1 yellow:green ratio).

WebThe law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene. This has has to do with 2 genes.

WebApr 28, 2024 · Somatic Cells Definition. Somatic cells are any cell in the body that are not gametes (sperm or egg), germ cells (cells that go on to become gametes), or stem cells. Essentially, all cells that make up an organism’s body and are not used to directly form a new organism during reproduction are somatic cells. The word somatic comes from the ... WebThe cell cycle culminates in the division of the cytoplasm by cytokinesis. In a typical cell, cytokinesis accompanies every mitosis, although some cells, such as Drosophila embryos (discussed later) and vertebrate osteoclasts (discussed in Chapter 22), undergo mitosis without cytokinesis and become multinucleate.
