- The developing egg cell of a plant with a diploid chromosome number 20 was treated with colchicine. A normal sperm cell subsequently fertilized this egg. How many chromosomes would you expect to find in the zygote? Explain.At the end of mitosis in Aedes aegypti, each of the daughter cells will have chromosomes; however, at the end of meiosis, each daughter cell will end up with chromosomes.How many homologous pairs of chromosomes would be in the zygote if it were a male organism? Explain.
- How 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?Each sperm of a tomato plant contains seven chromosomes. What are the haploid and diploid number for tomatoes? haploid=7 and diploid=14 haploid=14 and diploid=7 haploid=7 and diploid=49 haploid=3 and diploid=7The diagram below shows a cell during Meiosis II: a) What phase of Meiosis II is the cell in? How do you know? b) Assuming all of the chromosomes present during Meiosis II are shown in the figure above, how many chromosomes (counting homologous pairs as two chromosomes) does a gamete from this organism have? c) Draw the same cell during the same phase of Meiosis I. Label the elements
- A normal diploid cell from a chimpanzee has 48 chromosomes. How many chromosomes will be in a chimpanzee cell just before meiosis begins, after meiosis I, and after meiosis II? After which of these stages will the chromosomes have two chromatids?Truffles (Tuber borchi) have 2n=8 chromosomes. For the mitotic and meiotic stages below, draw the chromosomes and chromatids, and give the number of homologous pairs, chromosomes, and chromatids present. Be sure to differentiate homologous chromosomes by using size, shape, or other labeling mechanism. Metaphase of mitosis ( # homologous pairs # chromosomes # chromatids Anaphase of meiosis II – draw and count chromosomes for only 1 cell ( # homologous pairs # chromosomes # chromatidsConsider a cell in which nondisjunction occurs for all chromosomes during meiosis I. What would be the result of this event? Multiple Choice two diploid gametes two haploid gametes and one aneuploid gamete with an extra set of chromosomes four aneuploid gametes four haploid gametes
- Consider a diploid cell that has 2 n = 4 chromosomes: one pair of metacentric chromosomes and one pair of acrocentric chromosomes. Suppose that this cell undergoes nondisjunction, giving rise to an autotriploid cell (3 n). The triploid cell then undergoes meiosis. Draw the different types of gametes that could result from meiosis in the triploid cell, showing the chromosomes present in each type. To distinguish between the different metacentric and acrocentricchromosomes, use a different color to draw each metacentric chromosome; similarly, use a different color to draw each acrocentric chromosome.Consider a diploid cell that has 2 n = 4 chromosomes: one pair of metacentric chromosomes and one pair of acrocentric chromosomes.

Select all that apply. Reduction division occurs in meiosis only. Mitosis produces four daughter cells and meiosis only produces two. Gametogensis occurs in mitosis only. Meiosis produces four daughter cells and mitosis only produces two. Mitosis produces cells that are genetically identical to the parent cell whereas meiosis produces cells that only have half the genetic material of the parents. Both Mitosis and meiosis produce cells that are genetically identical to the parent cell.
