Question
Chapter 3, Problem 20P
a.
Summary Introduction
To determine: The possibility that some paternal mitochondria leak in the meiocyte.
Introduction: A meiocyte is a kind of cell that contrasts in a gamete by the process of meiosis. During meiosis, the diploid meiocyte splits into four genetically different haploid gametes.
b.
Summary Introduction
To determine: The way for testing the possibility.
Introduction: A reciprocal cross is breeding research designed to test the function of parental sex on a given inheritance pattern.
c.
Summary Introduction
To determine: The color that is used to denote cytoplasm containing wild-type mitochondria.
Introduction: The mitochondrion is a semi-autonomous double-membrane-bound organelle found in most eukaryotic organisms.

Mitotic nondisjunction can occur, particularly in tumor cells.
Assume a single nondisjunction event involving the X chromosome occurs in a cell undergoing mitosis in a human female.
First, consider the daughter cell with the smaller number of chromosomes:
How many total chromosomes will this cell have?
How many X chromosomes will this cell have?
Next, consider the daughter cell with the larger number of chromosomes:
How many total chromosomes will this cell have?
How many X chromosomes will this cell have?
This is a three part question:
Mitosis and meiosis are both processes of eukaryotic cell division, with the same names used to describe different stags.
a. What are the significant cellular and chromosomal events that occur during each stage of mitosis?
b. What are the similarities and differences between the events that occur during each stage of mitosis and the corresponding stage of meiosis I?
c. What are the similarities and differences between the events that occur during each stage of mitosis and the corresponding stage of meiosis II?
Consider the following two meiocytes in metaphase I, with crossover positions as indicated for cell A. Solid black lines indicate spindle microtubules. Assume blue
