Aplia Assignment: Genetic Recombination Due Today at 11 PM MDT Attempts: 64 3. Key characteristics of meiosis Keep the Highest: 6/7 In a human body, most clls that divide do so by mitosis. Only some cells ever undergo melosis. which of the following are cells that do not or cannot divide by melosis? Check all that apply. somatic cells such as hair follicle cells Triploid (3m cells Meiocytes In the third column of the following table, identify when the following four key events occur in a cell undergoing meiosis. For comparison, the second column describes when these events occur, if at all, in a cell undergoing mitosis. Event Sister chromatids become separate chromosomes. Each chromosome is duplicated into a pair of sister chromatids. Ss phase Crossing-over takes place.

Explanation / Answer

Somatic cells such as hair follicle cell do not undergo meiosis

Crossing over takes place during the Meiotic Prophase 1 (Pachytene)

Two sister chromatid separated from each other during Meiotic Prophase 1 (Pachytene)

The homologous chromosome are pulled toward opposite end during the ANAPHASE 1
