How many chromosomes are present in a daughter cell after meiosis I? d. How many chromatids are present in a daughter cell after meiosis II? e. How many chromosomes are present in a daughter cell after mitosis? f. How many pairs of homologous chromosomes are visible in the cell in metaphase of meiosis I?Chromosome structure is composed of the following Telomere Centromere Chromatids O All of the aboveMitosis produces 2 daughter cells that are identical to the starting cell. Explain how meíosis is different using this diagram to help you. 1) How many cells are created through meiosis? 2) Describe the chromosomes in each gamete at the end of meiosis? Are the set of chromosomes in a gamete identical to the starting cell like they are in mitosis? Are there the same number of chromosomes in each gamete as the starting cell?

- How many chromosomes and how many chromatids in the picture??if there are 9 chromosome pairs that undergo mitosis and meiosis, - how many chromatids are there in Prophase? -What is the chromosome number at Metaphase? -How many centromeres are there in Metaphase I? -How many univalents per pole at Anaphase? -What is the chormosome number at Telophase and Telophase I after cytokinesis?Draw a side-by-side comparison of mitosis and meiosis. Include 6 chromosomes in your drawings at the beginning of mitosis and meiosis. Be sure to label the following in each of your drawings where appropriate: chromosomes/chromatin/sister chromatids, mitotic spindle, asters, centromeres, microtubules, centrosomes, kinetochore, and nuclear membrane.
- If you were given a cell with 9 chromosome pairs, find the following: centromeres during mitosis prophase chromatids during meiosis metaphase I chromosome number during mitosis metaphase bivalents during pachytene chromosome number during meiosis telophase IHow many chromosomes does a human normal haploid cell have? How many chromosomes does a human normal diploid cell have? How many are thesex chromosomes within each of them?Draw a single duplicated chromosome, labeling the chromatid(s) and centromere
- 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?In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides?+ 1.
