Summary Introduction

To review:

Types of gametes plants can make having three copies of a chromosome and three copies of the gene TTt for height on that chromosome which are also heterozygous for the seed color Yy.

Introduction:

When an individual is found with three copies of a chromosome instead of two then it is an example of trisomy. Further, any gain or loss in the chromosome numbers from the 46 (normal) is referred to as aneuploidy. The common form of aneuploidy is trisomy. Aneuploidy occurs due to improper segregation of chromosomes.
