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, but there are only 22 pairs of homologous autosomal chromosomes. The additional 23rd pair is the sex chromosomes, X and Y. If this pair is made up of an X and Y chromosome, then the pair is not truly homologous because their size and types of genes differ slightly.s this karyotype displays, a diploid human cell contains 23 pairs of homologous chromosomes. The cell has two sets of each chromosome; one of the pair is derived from the mother and the other from the father.
