- QUESTION 8 Match the stage of meiosis to its description. Watch for "cell" versus "cells". Singular versus plural is a clue that will help you pick the right roman numeral. homologous chromosomes line up next to each other as tetrads along the mid- line of the cell DNA condenses, tetrads form as homologous chromosomes come together and exchange DNA parts in crossing over, nuclear membrane disintegrates A. Early Interphase B. Late Interphase one of each homologous pair reaches the end of the cell, new nuclear membranes form, and the cell membrane begins to pinch in C. Prophase I v DNA condenses in two cells, nuclear membranes disintegrate D. Metaphase I the copies of the chromosomes (daughter chromosomes formerly known as sister chromatids) split apart and move towards the ends of two cells E. Anaphase I v the cell divides into two cells, chromosomes decondense F. Telophase I G. Interkinesis tetrads separate and homologous chromosomes begin to move in opposite directions in a cell H.…QUESTION 2 Listed below are some sex chromosome combinations. For each combination, state whether the individual is male or female in humans and also in Drosophila (assume the flies have two sets of autosomes).
