Question
Chapter 2, Problem 18PDQ
Summary Introduction
To review:
The probability that in anorganism (haploid number of chromosomes or n is10), a spermformed will contain all 10 chromosomes, withcentromeres derived from maternal homologs.
Introduction:
Meiosis is the process of cell division, in which a single cell dividesinto two phases and it leadsto the production of four daughter cells. The daughter cells contain half the amount of parental cell’s genetic information. Meiosis occurs during the formation of gametes (a sperm and an egg).

What is the probability that, in an organism with a haploid number of 10, a sperm will be formed that contains all 10 chromosomes whose centromeres were derived from maternal homologs?
Though an individual with abberations such as Robertsonian translocation may be phenotypically normal, they can generate gametes through meiosis that have atypical organizations of chromosomes, resulting in recurrent fetal abnormalities or miscarriages. Why, despite these Robertsonian translocations, are affected cells still able to generate typical gametes through meiosis?
If these segregation patterns are equally likely, what is the probability that a gamete produced by the individual who carries the translocatedchromosome will result in a viable offspring with a normal phenotype?
