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.
44. - - -. In humans, there are 23 chromosomes in one set. Of these, one is a sex chromosome, and the other 22 are autosomes. So there are 22 autosomes in a human gamete (spermatozoon or ovum). In the zygote and all the body cells subsequently formed from the zygote, there are two sets (the diploid condition) and therefore 44 autosomes (two genetically different versions of each of the 22).
