Detailed explanation-1: -Genes are found on tiny spaghetti-like structures called chromosomes (say: KRO-moh-somes). And chromosomes are found inside cells. Your body is made of billions of cells.
Detailed explanation-2: -Locus. Locus is a term that we use to tell us where on a chromosome a specific gene is. So it’s really the physical location of a gene on a chromosome.
Detailed explanation-3: -The basic unit of heredity passed from parent to child. Genes are made up of sequences of DNA and are arranged, one after another, at specific locations on chromosomes in the nucleus of cells.
Detailed explanation-4: -Humans typically have 23 pairs of chromosomes, or 46 chromosomes in total. Chromosomes are made up of long strands of DNA, which contain all the body’s genes.
