Question
Chapter 4.3, Problem 14BYGO
Summary Introduction
To determine:
Two diseases caused due to nondisjunction of autosomes, and two diseases caused due to nondisjunction of sex chromosomes.
Introduction:
Sometimes genetic defects caused due to aneuploidy, which is an abnormal chromosomal number in the zygote. Nondisjunction is the cause of aneuploidy. Nondisjunction is caused due to improper separation of chromosomes (autosomal or sex chromosomes) during meiosis. Due to this, both pairs of the chromosome go to the same cell.
