You asked: Why chromosomes play an important role in our inherited traits?

Your chromosomes contain the blueprint for your body – your genes. Almost every cell in the human body contains a copy of this blueprint, mostly stored inside a special sac within the cell called the nucleus. Chromosomes are long strands of a chemical substance called deoxyribonucleic acid (DNA).

Why is genetic inheritance important?

Genetics helps to explain: What makes you unique, or one of a kind. Why family members look alike. Why some diseases like diabetes or cancer run in families.

How does genetics explain our inherited traits?

The inheritance of each trait is determined by ‘factors’ (now known as genes) that are passed onto descendants. Individuals inherit one ‘factor’ from each parent for each trait. A trait may not show up in an individual but can still be passed onto the next generation.

How is genetics used in everyday life?

Scientific research has today advanced further and identified genes coding for the way muscles in our body respond to diet and training, skin types and their response to nutrition, the control of hair fall, risk of diabetic complications, obesity, addictions and a lot more. “This actually came to us from the public.

Is genetic material responsible for inheritance?

What is the primary function of a chromosome?

The most important function of chromosomes is to carry the basic genetic material – DNA. DNA provides genetic information for various cellular functions. These functions are essential for growth, survival, and reproduction of the organisms. Histones and other proteins cover the Chromosomes.

Is DNA responsible for mutation?

Over a lifetime, our DNA can undergo changes or mutations in the sequence of bases: A, C, G and T. This results in changes in the proteins that are made.

What are 4 examples of inherited traits?

INHERITED TRAITS are those traits that are passed down from parents to their offspring.

  • EX. In humans- eye color, hair color, skin color, freckles, dimples, etc. are all examples of inherited traits.
  • EX. In animals- eye color, fur color and texture, facial shape, etc. are examples of inherited traits.

What traits are genetic?

Most traits are determined by more than one gene. For example, skin color and height are determined by many genes. Some phenotypes however, are determined by a single gene.
