Select one or more: a. Mitosis results in 2 haploid cells O b. If a parent cell with 10 chromosomes undergoes mitosis, each offspring cell will have 10 chromosomes O c. At the start of meiosis, a human cell will have 46 chromosomes and 92 chromatids d. The purpose of mitosis is the production of gametes e. In Meiosis, crossing over occurs during Meiosis II f. Meiosis only occurs in the testes and ovariesUsing the symbols above: 1. Given: Adult diploid cell (2n = 8) 2.

The statement is true for meiosis II only D. The statement is true for mitosis only E. The statement is true for mitosis and meiosis I2. Place this events in the correct order that they occur during homologous recombination: A. Resolvase cuts all four chromatidsB. Strand invasion causes one strand of the uncut chromatid to form a D loop C. Spo11 causes a double-strand break in a nonsister chromatidD. Branch migration lengthens the heteroduplex regionE. Recombinant chromosomes separate from each otherOnly some cells derive from a mitosis event.. 1. Which statement is most correct regarding the difference between mitosis and meiosis? O Meiosis can produce any cell type, while mitosis can only make gametes (sperm/egg cells) * Mitosis essentially clones a cell (makes an identical copy), while meioisis is a ma O complex process that divides up a cell's set of chromosomes into gametes (sperm/egg cells) ODNA replication is required for mitosis but not for meiosis ODyads are seen in mitosis but not meiosis 2 What distinguichon hon
