Question

difference between homozygous and heterozygous organisms with examples

Answer 1

Individual organisms carrying two identical alleles (for example TT or tt) are homozygotes, and those with dissimilar alleles(for example Tt) are called heterozygotes

Answer 2

and ex is
a very tall man and a very tall woman who have a child. This child grows into an adult and is very tall as well. It could be said that the child's height is a homozygous means AA or aa it is homozygous for that trait
HETEROZYGOUS  Heterozygous is a trait when two different kinds of alleles combine to form a trait. 
and ex is
