Question

• Deletion chromosomes are useful for what purpose?

Expert Solution
Step 1

Genetics is the branch of biology which deals with genes, heredity, and genome in the organism. Genes contain all information of proteins forms inside the body. It contains genetic information that passes from parents to offspring. It is a study of traits like eye color, hair color, the risk for the disease is passed to their children, skin color, etc.

Step 2

Both heterozygous and homozygous terms describe allele pair. If individuals carry two similar alleles like TT or tt are known as homozygotes or homozygous. If individuals carry different alleles like Tt this will know as heterozygote or heterozygous. 

Deletion causes chromosomal rearrangements that alter gene expression. The effects of deletions depend on their size.
