Problem 1: Consider a diploid organism with a diploid number of 16. Show your work and/or explain logic on all parts.
A. How many chromatids will be present in a typical cell at mitotic metaphase?
B. How many dyads are present in a metaphase I cell of meiosis?
C. How many tetrads are present in a prophase I cell in meiosis?
D. How many dyads are expected in each product cell at the end of meiosis I?
E. How many monads are expected in each product cell at the end of meiosis II?
Problem 2: The diploid number of a certain species is six, including two "long", two "medium" and two "short" chromosomes.
Make a drawing of a diploid cell from that species as it would appear in metaphase of mitosis. Make sure the chromosomes are in the correct form (monad or dyad) and that the cell has the correct ploidy.
Make a drawing of a diploid cell from that species as it would appear in Metaphase I of meiosis. Make sure the chromosomes are in the correct form (monad or dyad) and that the cell has the correct ploidy.
How many chromosomes of each "type" (length) would be in a triploid cell from this species? Explain your answer based on your understanding of ploidy.
