of chromosomes to each daughter cell which results from cell division.This processis
responsible for the transfer of genetic information to the daughter cells. The first 22
pairs of chromosomes are known as autosomes.The 23rd pair of chromosomesis the
pair which contains the genetic information for gender. This pair contains
the genetic information which delineates between the male and female genders.
Females have two X chromosomes (XX) and males have an XY chromosome pair.
Autosomal chromosomes are said to be autologous. This means they do not carry
genetic information pertaining to gender. Autosomal genetic diseases are carried on
the first 22 pairs of chromosomes. Sex-linked diseases are only carried on
the 23rd pair of chromosomes. The autosomal chromosomes are nearly identical to
one another and are considered homologous to one another. Each autosomal
chromosome in a pair carries identical genes.These two genes are known as alleles.The
alleles occupy the same site on each partner of the chromosome pair and code for the
same genetic trait or physiologic function. Alleles can be dominant or recessive. One
allele may be dominant and the other recessive, or they both may bedominant or both
recessive.The dominant alleles' genetic code will always manifestin the individual's
phenotype. The information in the recessive allele is typically notexpressed in the
phenotype unless both alleles are recessive. For the purpose of clarity in use, the
dominant gene is assigned a capital letter and the recessive geneis assigned a lower
