the core of the virus is the capsid. The genome surrounds the capsid, and the virus may or may not have an outer layer called an envelope. the genome is surrounded by a protein coat called a capsid, which may or may not be surrounded by an envelope.
Can identical twins have different hair and eye color and still be identical? Me and my twin sister are almost exactly identical in every way except our hair and eye color. I have blond hair and gray-blue eyes, and she has light brown hair and gray-green eyes. Our doctor says we are identical but no one thinks we are because we have different an eye colors. So if anyone knows if identical twins can be identical even if they have different hair and eye colors i'd love to know what you think. Update: we are both girls by the way.
All blue eyes are not created equal because eye color is determined by many different gene combinations, as seen in the image below: The colored part of the eye is called the iris. The iris has pigmentation that determines the eye color. Irises are classified as being one of six colors: amber, blue, brown, gray, green, hazel, or red. Often confused with hazel eyes, amber eyes tend to be a solid golden or copper color without flecks of blue or green typical of hazel eyes.
