- Distinguishing Meiosis I from Meiosis I| How do you know what is meiosis I and what is meiosis II? Here are some hints to help you determine how to identify if a cell is undergoing meiosis I or meiosis II. • In prophase l and metaphase I, the chromosomes are found in their homologous pairs. In prophase Il and metaphase ll, there are single duplicated chromosomes. • In anaphase l and telophase I, the chromosomes are duplicated (shaped like Xs). In anaphase ll and telophase II, the chromosomes are not duplicated. Take a look at the picture, and then answer the questions How many chromosomes will be in the gamete produced when this cell has finished meiosis?

- Discuss Concepts One of the human chromosome pairs carries a gene that influences eye color. In an individual human, one chromosome of this pair has an allele of this gene that contributes to the formation of blue eyes. The other chromosome of the pair has an allele that contributes to brown eye color (other genes also influence eye color in humans). After meiosis in the cells of this individual, what fraction of the nuclei will carry the allele that contributes to blue eyes? To brown eyes?arrow_forwardWhat is independent assortment during meiosis 1? POSSIBLE PC if two individuals mate, and each is capable of producing over 8 million potential gametes, the random chance of any one sperm and egg coming together is a product of these two probabilities - some 70 trillion different combinations of chromosomes in a potential offspring O a process where a single cell divides twice to produce four cells containing half the original amount of genetic information O homologous pairs of chromosomes line up in random orientations at the middle of the cell as they prepare to separate O swapping of genetic material 4. 1 2 3 4. e to searcharrow_forward..explain why meiosis occurs only in specialized cells (gametes), and that the overall goal of meiosis is to make haploid cells for sexual reproduction • ..outline the sequence of key chromosomal movements and rearrangements during the two meiotic divisions, identifying key similarities and differences between meiosis and mitosis • ..describe the ploidy of a cell before and after meiosis I and meiosis II, and how ploidy changes after separation of sister chromatids and homologous chromosomesarrow_forward
