Meiosis

Question 1

What information did you include in your response?

Revolt · Accepted Answer

Crossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis.; Crossing over results in a new combination of genetic information for the cell for a specific trait.; Crossing over ensures that organisms are not identical from generation to generation.; Genetic recombination allows for a variation in genetic material that is passed through the generations.

Question 2

What information did you include in your response?

Revolt · Accepted Answer

Independent Assortment is the second law of inheritance; Traits are passed from parents to offspring independently of one another.; Independent assortment is random and occurs during Metaphase I of meiosis.; There are two possible alignments for the chromosomes.; Since the alignments are random and not assigned, genetic variation occurs.

Question 3

Revolt · Accepted Answer

anaphase I; Selection 1: anaphase I; Selection 2: prophase I; Selection 3: telophase I; Selection 4: metaphase I

Question 7

Chromosomes are lined up by spindle fibers. Nuclear envelope forms around each set of DNA. Sister chromatids are pulled apart. Centromeres move toward the poles of the cell.
