a.

Summary Introduction

To determine:  The unusual features that distinguishes this pedigree from other pedigree charts.

Introduction. The genes are the sequence of nucleotides that are present on the chromosomes and encode for a specific protein that plays a crucial role in the functioning of the different processes in an organism. The gene is located at specific gene loci and can be structural or regulatory in nature

b.

Summary Introduction

To determine:  The site of mutant DNA responsible for this phenotype in the cell.

Introduction. The mutation is the change in the nucleotide sequence of the gene, which results in either the formation of a defective protein or no protein at all. The mutation can also alter the regulation of certain genes leading to their hyperactivity or hypoactivity.
