Figure 3 shows 23 paired chromosomes of a male and a female. The members of each pair of chromosomes are both similar and different: Each chromosome in the pair contains varying forms of the same genes, at the same location on the chromosome. A gene that influences hair color, for example, is located on both members of one pair of chromosomes, at the same location on each. However, one of those chromosomes might
carry the gene associated with blond hair; the other might carry the gene associated with brown hair.
Figure 3 The Genetic Difference Between Males and Females Set (a) shows the chromosome structure of a male, and set (b) shows the chromosome structure
of a female. The last pair of 23 pairs of chromosomes is in the bottom right corner of each set.
Notice that the Y chromosome of the male is smaller than the X chromosome of the female. To
obtain this kind of chromosomal picture, a cell is removed from a person’s body, usually from
the inside of the mouth. The chromosomes are stained by chemical treatment, magnified
extensively, and then photographed.© CMSP/Custom Medical Stock Photo-All rights reserved
Do you notice any obvious differences between the chromosomes of the male and those of the female in Figure 3? The difference lies in the 23rd pair. Ordinarily, in females this pair consists of two chromosomes called X chromosomes; in males the 23rd pair consists of an X chromosome and a Y chromosome. The presence of a Y chromosome is one factor that makes a person male rather than female.
