A student is developing a model of sex cell formation. Which of the following conclusions can be made from the student's model of why the DNA of the daughter cells is different from the DNA of the parent cell? *
A. Stage 1 is prophase I. A tetrad is formed and crossing over occurs. Genetic diversity is achieved by exchanging genetic information of sister chromatids.
B. Stage 2 is metaphase I. Chromosomes are pulled to opposite ends of the cell. Genetic diversity is achieved by separating genetic information of the chromosome.
C. Stage 3 prophase II. Sister chromatids line up in the middle of the cell. Genetic diversity is achieved by exchanging genetic information of sister chromatids.
D. Stage 4 is metaphase II. Alleles in each gamete have different genetic information from the parent cell, creating genetic diversity.
