- Use the shapes below to answer Question number 2. Please be accurate and complete it CORRECTLY. Don’t use previous answers.arrow_forwardGive typing answer with explanation and conclusionarrow_forwardYou observe a stickleback embryo and follow the fate of one cell (cell A) at the 64 cell stage. The descendants cells of cell A eventually form the spines on the back of the fish as an adult. In a second embryo you remove the cell (cell B) that is right next to the cell that will form the spines. In this fish the spines do not form, although the cell that would form normally them (cell A) survives. What has happened? Group of answer choices A. Cell B's fate is not determined B. Cell B fails to induce cell A to form the spines C. Cell B fails to differentiate to form the spines D. Cell A fails to induce cell B to form the spinesarrow_forward

A single tetrad is shown with a pair of homologous chromosomes that have been duplicated as sister chromatids. Red chromosomes indicate maternal DNA, and blue chromosomes indicate paternal DNA. Use the passage to answer the question. Once the animal cell has completed meiosis II: A. half of the gametes will contain recombinant chromosomes. B. none of the gametes will contain recombinant chromosomes. C. all of the gametes will contain maternal DNA.
