Chapter 9.4, Problem 1LO
Summary Introduction

To determine:

The term non disjunction and how it is responsible for the formation of abnormal chromosomal number.

Introduction:

Humans cell contain 46 chromosomes (2n) and these are diploid in nature but at the time of fertilization only 23 (n) chromosomes are received from mother and 23 (n) chromosomes are received from father to form a zygote by the process of meiosis.

Zygote is formed by the transfer of male gamete (sperm) and female gamete (ova). The ova and sperm are haploid (n) and form a diploid zygote (2n). Zygote receives 46 chromosomes. Some humans are born with abnormalities as they receive abnormal chromosomal number in their cell. Abnormal chromosome is formed when chromosome fails to separate during meiosis and is known as non-disjunction.

Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.
