You are here. The Planets in Natural Colors. Several teachers and students have asked what the planets look like in true or natural colors. They've noticed that each planet's appearance can vary greatly in photographs, and that many of the photographs are labeled as a false-color view. Many times scientists enhance the colors, or contrast of an image to draw out more detail.
Human cells contain 23 pairs of chromosomes. Most of an organism's chromosomesâgenerally all except for one pairâare called autosomes, which are the same in males and females. Humans have 22 pairs of autosomes. Many organisms also have a pair of sex chromosomes, which differ between males and females. In humans, a female has two identical sex chromosomes. A male has one sex chromosome that is like those of females, and one that is smaller and differently shaped.
Humans have a total of 46 chromosomes in each body cell; 44 of these are autosomes. You get one set of 22 autosomes from your mom and another set of 22 from your dad. It is often easier to think about our autosomes in pairs because even though we have 44 autosomes, we actually only have 22 types. We have two copies of each type of autosome, one from each parent. Two chromosomes of the same type, called homologous chromosomes, are the same size and shape and have the same genes. Our paired autosomes are numbered 1 through 22.
