Summary Introduction

Introduction:

 

In humans, the chromosomes are diploid, which means there are two sets of chromosomes in the cells. Meiosis is a type of cell division, in which the number of chromosomes is reduced to haploid, which means a single set of chromosomes is present.

A) Quiescent Anaphase Telophase Telophase phase Metaphase Prometaph The maternal and paternal chromosomes of each homologous pair separate and reach the poles of the cell, nuclear envelopes form around them, and cytokinesis follows to produce daughter cells.
During metaphase 1,—————— align on the metaphase plate.
D. centromere QUESTION 8 Match the stages of mitotic cell division to the descriptions of those stages. v chromosomes attach to spindle fibers across the middle of the cell chromosomes are not yet duplicated so chromosomes only look like a line, only one pair of centrioles in cell A. Telophase cell membrane is pinching in forming a peanut-shaped cell, daughter v chromosomes reach the poles and new nuclear membranes are forming around them B. Late Interphase C. Early Interphase the nuclear membrane is breaking down, chromosomes are |condensing, centrioles are building microtubule "highways" (spindle fibers) D. Metaphase E. Anaphase chromosomes are duplicated so chromosomes look like an "X", two pairs of centrioles and double the amount of organelles fill the cell F. Prophase v cell is dividing into two identical cells G. Cytokinesis daughter chromosomes are beginning their migration to the poles on spindle fibers QUESTION 9 How do the two cells formed by a mitotic cell division compare…
