Question

The figure below shows chromosomes in a cell produced by some organism. Letters represent different kinds of genes; upper/lowercase letters represent different alleles for the same gene: e.g., purple allele (P) vs. white allele (p) for a flower color gene. 1. How many chromosomes do you see? 2. As drawn, is this cell haploid or diploid? 3. On what did you base your answer to #2 above? 2n = 4. What is the diploid number for the species in which this cell might be found? 5. What is the haploid number for the species in which this cell might be found? 6. What type of cell division produced this particular cell? (mitosis? Meiosis I? meiosis II?) 7. In the space below, please draw the cell with chromosomes and alleles as they would appear in the metaphase stage of cell division that gave rise to the cell shown above. Be sure to include spindle, aster, and the letters representing alleles on the chromosomes
I need hep with the answers to these mitosis and meiosis questions, any added explanation would be super helpful!

Answer 1

1. Totally 6 chromosomes are seen.

2. This cell is haploid since there is only one set of chromosome.

3. It is haploid because there is only one allele shown. Say A and a are allelic pair. After segregation and meiosis, the cells will get either A or a. If only one of the allelic pair is seen then it is haploid in nature. If it is diploid, we can see both A and a in a cell.

4. Diploid number 2n = 2*6 =12

5. Haploid number n = 6

6. Meiosis II - it is a reduction process and produces haploid gametes.
