( A woman having Turner syndrome.Use the following information as the basis for answering the question: A diploid eukaryotic organism has 4 unique chromosomes. Chromosome I is metacentric, chromosome II is telocentric, chromosome III is submetacentric, and chromosome IV is acrocentric. Draw a detailed picture of a germ cell from this organism in Metaphase of Mitosis and label all chromosomal and cellular components. Be sure to label each chromosome (I, II, III, or IV) and include the following in your drawing: centrosomes, 3 kinds of microtubules, metaphase/equatorial plate, and plasma membrane. Use the letter p to indicate a paternal chromosome and m to indicate a maternal chromosome.
