Homozygosity

=Homozygosity=

In diploid organisms, **homozygosity ** is the property of having identical alleles for a particular locus on both homologous chromosomes. Organisms that are **homozygous ** for any particular locus are termed **homozygotes **. Homozygosity is the opposite of heterozygosity, where two //different// alleles for a given locus are carried on homologous chromosomes.

 If the homozygote carries two dominant alleles for a locus then it is said to be **homozygous dominant **; if it carries two recessive alleles then it is **homozygous recessive **.

 A homozygous parent can only offer one allele, for the locus at which it is homozygous, to its offspring.
