- All of the above 8. Which is the correct description of the human chromosome number? * O2n =23 (where n=23, the number of different numbered human chromosomes) O2n = 46 (where n=23, the number of different numbered human chromosomes) O 4n = 23 (where n=23, the number of different numbered human chromosomes) O4n = 46 (where n=23, the number of different numbered human chromosomes) Any comments please use this space (e.g. to clarify an answer or point out w issues on questions, etc.)Part I. Complete the following table of chromosome number in various species (1 pt. each) Number of chromosomes in Number of Number of chromosomes in homologous chromosome pairs haploid cells (n) in diploid cells Species diploid cells (2n) Fruit fly Leopard Frog 2n = 26 Housefly Monkey 2n = 8 1. 2. 3. 4. 5. 6. n= 6 7. 8. n = 21 Bat 9. 22 pairs 39 pairs 104 pairs 15. 18. 20. 10. 11. King Crab Chicken 12. 13. 14. 16. n= 30 n= 32 Camel 2n = 70 Goat 17. Armadillo 19. Part II. Provide the correct number of chromosomes, chromatids, and DNA molecule Mitosis: 2n = 70 21. Number of chromosomes after Prophase? 22. Number of chromosomes after Anaphase? 23. Number of chromatids after Metaphase? 24. Number of chromosomes after Cytokinesis? 25. Number of DNA molecule after Anaphase? Meiosis: 2n = 78 26. Number of chromosomes after Meiosis l? 27. Number of chromatids after Meiosis I? 28. Number of chromosomes after Meiosis II? 29.

How would the number of chromosomes in the fox's body cells compare to the number of chromosomes in its gametes? Top of Form Its body cells and gametes would both have 18 chromosomes. Its body cells and gametes would both have 36 chromosomes. Its body cells would have 18 chromosomes, and its gametes would have 36 chromosomes. Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes.
- Chewbacca from Starwars is a part of a species that has 64 chromosomes for its diploid number. What would it haploid number be?As shown gives the number of chromosomes in a haploid set of chromosomes. What is the lowest number in the table? What is the highest number? Most cells in plants are diploid, having two sets of chromosomes,so the number per nucleus should be doubled. How many chromosomes are present in each diploid potato nucleus? If a potato plant has 1 million cells, each with one diploid nucleus, how many chromosomes are present in the entire plant?. A redwood tree, Sequoia sempervirens is hexaploid with a total of 66 chromosomes. Considering this, how many chromosomes did the tree inherit from each of its parents? How many chromosomes can be expected to be in each of its gametes? How many chromosomes are likely to be in each somatic cell of the tree's offspring?
- In mice, 2n = 40. If a mouse cell divides by mitosis, it will produce two daughter cells that each have ________ chromosomes. If a mouse cell divides by meiosis, it will produce four daughter cells that each have ________ chromosomes. Type the appropriate number to fill in each blank (e.g., 40).Select two that apply. Which of the following generate genetic diversity in meiosis? homologous chromosomes are separated during anaphase II homologous chromosomes align individually during metaphase II O bivalents align independently from other bivalents during metaphase I sister chromatids exchange genetic material during prophase I homologous chromosomes exchange genetic material during prophase I meiosis goes through two rounds of divisionHere is a strawberry karyotype - ignore the different colours. How many chromosomes are shown in the figure? What is the ploidy of this type of strawberry? How many alleles could an individual strawberry have at each locus? Finally during the G2 stage of cell division, how many double helixes would be in this picture if you drew them over the chromosomes? Many domesticated plants are polyploid - give one possible reason why this might be the case, with a focus on using genetic principles to reason it out (i.e., you don't have to be right per se, you have to build an argument based on what you've already learned).
- Figure 1. Showing a homologous pair of chromosomes that carry two linked genes. Here we can see that one chromosome carries A and Balleles, while the other homologous chromosome carries a and b alleles. This is much more informative than just giving the genotype of AaBb. Another way to symbolize the arrangement of alleles on a chromosome is to give the symbols for alleles on one chromosome above a horizontal line, and the symbols for the alleles on the homologous chromosome below the horizontal line. For example: A Figure 2. Showing the arrangement of alleles for a pair of linked genes. Here we can see that, exactly like the example in Figure 1, one chromosome carries A and B alleles, while the other chromosome carries a and b alleles. 1. Suppose that Gene G and Gene D are linked. If the genotype of an organism is GGDD, use both types of symbols you learned in Figure 1 and Figure 2 above to show the arrangement of alleles for this organism.Random Fusion of Gametes Someone out there Two mating individuals have the same kinds and same number of chromosomes, but those chromosomes are not exactly identical. Because individuals possess different variations of genes, the random fusion of gametes (fertilization) from any two individuals will result in more genetic variety in the offspring. Through fertilization the diploid set number is recreated with the offspring receiving one chromosome of a homologous pair from one parent, and the other chromosome of the pair from the other parent. is more genetically like you than either of your parents. ? QUESTION To keep the example relatively simple, let's consider only one of the homologous pairs of the human-the A chromosome. (Actually, human chromosomes are referred to by numbers from 1 to 23.) Al came from 1. Where did chromosome A2 come from? A' A2 your father 2. Where did chromosome A4 come from? 3. What are your possible gametes? You What are your mate's possible gametes? 4.…X and Y chromosomes have some genes in common. These genes are inherited in a pseudoautosomal pattern. With this phenomenon in mind, discuss whether or not the X and Y chromosomes are really distinct linkage groups. Give answer?
