Because an individual is diploid and possesses only two homologous chromosomes for any given gene locus.

Vedclass · Answer

(B) In a diploid organism,every chromosome exists in a pair,known as homologous chromosomes. Since a gene locus is located at a specific position on a chromosome,an individual can only carry a maximum of two alleles for a single gene—one on each homologous chromosome. Multiple allelism is a phenomenon observed only at the population level,where more than two alternative forms of a gene exist within the gene pool of a species.

Genotype	Blood group
$I^{A} I^{A}$	$A$
$W$	$A$
$I^{B} I^{B}$	$B$
$X$	$B$
$I^{A} I^{B}$	$Y$
$Z$	$O$

Even if a character shows multiple allelism,an individual will only have two alleles for that character. Why?
