Complete the following statements using as many of the following terms as are appropriate: mitosis, meiosis I (first meiotic div

goldenfox [79]

Answer:

a. The spindle apparatus is present in cells undergoing mitosis and meiosis. the spindle is crucial for chromosome sorting.

b. Chromosome replication occurs just prior to mitosis and meiosis I. DNA needs to be copied during S fase to have enough DNA and transfer it to the daughter cells.

c. The cells resulting from mitosis in a haploid cell have a ploidy of n.

Mitosis produces identical cells.

d. The cells resulting from meiosis II in a diploid cell have a ploidy of n. meiosis is the only process that causes chromosome reduction (assuming no errors).

(e). Homologous chromosome pairing regularly occurs during meiosis I. Each daughter cell needs 1 chromosome of each kind

(f). Non-homologous chromosome pairing regularly occurs during none. This is kind of an error.

(g). Physical recombination leading to the production of recombinant progeny classes occurs during Meiosis I

(h). Centromere división occurs during meiosis II and mitosis

(i) Non-sister chromatids are found in the same cell during meiosis II
