sections of DNA in the chromosome that carry the information for the traits of an organism such as hair color, eye color, height, etc. Genes, like the chromosomes they make up, are in pairs. One half of the pair comes from one parent and one half from the other parent and are joined into pairs when the sperm fertilizes the egg during reproduction. Each member of a pair of genes is called an allele.
A gene is a segment of DNA coding for a particular protein. Alleles are different forms of a given gene. Every gene can have two or more than two alleles, but, alleles exist only in pairs to produce a phenotypic effect( an observable trait). For example, the gene coding for height has two alleles -. (i) T - which is the dominant allele and leads to a tall phenotype in homozygous (TT) or heterozygous (Tt)condition ,and. (ii) t -which is the recessive allele, and leads to a dwarf phenotype only in homozygous(tt) condition.
