9. What are the two ways in which meiosis brings about genetic recombination and which stage or stages of meiosis is responsible?…
2. What are the possible genotypes of the offspring from mating of the following individuals? (the x refers to the mating. In the first, you would place EE along the top and ee on the side or vice versa).…
4. Describe the two events that occur during meiosis 1 that increase genetic diversity in gametes. Also, state why these events are so important to life on Earth.…
1.c. Based on what you know about the principles of Mendelian genetics, predict the phenotypic ratio that you would expect to see for the F1 offspring of this cross and describe the phenotype of each fly.…
Question: How does mitosis produce new cells, and how is mitosis the same and different?…
Part 2: For this portion, please sketch a cell with 4 total chromosomes, 2 homologous pairs, going through the process of meiosis. You should label your work and include 2-3 events that are specific to each phase of meiosis. You will also want to include the total number of chromosomes in the parent and daughter cells. For this portion, please include a crossing over and independent assortment event and label the phases of meiosis where these processes take place.…
An organism with three pairs of homologous chromosomes statistically could produce __________ different gametes strictly on the basis of independent assortment. 8…
24) How do cells at the completion of meiosis compare with cells that have replicated their DNA and are just about to begin meiosis?…
4) What is the genotypic and phenotypic ratio from the F2 of a monohybrid cross?…
1. In selective breeding you are relying on the natural random distributions of genes in the mating process. By rewarding some combinations and by discouraging others you can arrive at an organism with traits that are predictably more desirable than those of their ancestors. In genetic engineering you are forcibly inserting genes into the procreation process to create a new organism. These genes may be from an animal of the same species, a different animal/plant, or (in theory) genes can be designed from scratch.…
10. For cells to stay the same size from generation to generation, what two things must be coordinated?…
3. Why did you use the same number of beads and position for the centromere for the two long homologous chromosomes? To represent the set of genes for the mother and father.…
* A gene's specific location along the length of a chromosome is called the gene's locus…
Unit 5 Free Response Meric Pope Meiosis 1 and Mitosis are very similar events, however, they have certain differences. One difference is crossing over. Meiosis 1 does cross over and because of that, it creates genetic changes. Mitosis , on the other hand, does not cross over. Something else that is different is the way it occurs.…
Use Ch. 5 of BioInquiry and the “Comparing Mitosis and Meiosis” video as resources for Part 1 of this assignment. Write 75- to 100-word answers to the following questions.…
