What chromosomes control our characteristics?
A gene is a short length of DNA found on a chromosome that codes for a particular characteristic or protein. Alleles are variations of the same gene. For example, eye colour is the gene but blue, green, brown etc.
What chromosome determines body type?
The X and Y chromosomes, also known as the sex chromosomes, determine the biological sex of an individual: females inherit an X chromosome from the father for a XX genotype, while males inherit a Y chromosome from the father for a XY genotype (mothers only pass on X chromosomes).
Do chromosomes determine characteristics?
These sections of DNA th at contain information that determine your physical features are called genes. Since you have two pairs of chromosomes, you also have two pairs of genes, one from your fath er and one from your mother. These pairs of genes then determine certain physical features or traits.
What does the 5 chromosome do?
Chromosome 5 spans about 181 million base pairs (the building blocks of DNA) and represents almost 6% of the total DNA in cells. Chromosome 5 is the 5th largest human chromosome, yet has one of the lowest gene densities….

What determines your body type?
There are so many factors that can determine our body shape: genetics, lifestyle, sex and age. Some people can eat fried foods and junk every day but never gain weight. Some people tend to accumulate weight around the hip, others on the belly.
How is DNA responsible for human characteristics?
DNA contains the information to make proteins, which carry out all the functions and characteristics of living organisms. DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein.
