Question
Chapter 3, Problem 33P
Summary Introduction
To determine: The proportion of his children will have the same karyotype that he has.
Introduction: Karyotyping is the process by which photographs of chromosomes are taken to determine the chromosome complement of an individual, including the number of chromosomes and any abnormalities.

Suppose you discover two interesting rare cytological abnormalities in the karyotype of a human male. (Akaryotype is the total visible chromosome complement.) There is an extra piece (satellite) on one of the chromosomes of pair 4, and there is an abnormal pattern of staining on one of the chromosomes of pair 7. With the assumption that all the gametes of this male are equally viable, what proportion of his children will have the same karyotype that he has?
You are an allele on a single uncondensed chromosome in a Yellow fever-carrying mosquito (Aedes aegypti) diploid cell (2n = 6). Demonstrate in as much detail as possible:
(1) how you will get to each genetically identical diploid cell of the multicellular offspring.
(2) how you will get to the next generation of sexually reproduced progeny.
A woman with a balanced reciprocal translocation of Chromosomes 4 and 20 (karyotype, right panel below) is
trying to reproduce with a man of normal karyotype (left panel below). Please answer:
1) What are the karyotypes of their respective gametes ()?
2) What are the karyotypes of their potential offspring ()?
3) What are the percentages of each karyotype (gametes and offspring) ()?
4) Indicate which karyotype (of the offspring) will be lethal, carrier or normal ().
5) Do she have reduced fertility and why?
