Distinguish between homozygosity and heterozygosity at a sin

Distinguish between homozygosity and heterozygosity at a single geneticlocus in a diploid organism. If an individual is homozygous at one genetic locus on chromosome 12, is thatsame individual homozygous at all loci on chromosome 12?

Solution

When two alleles of a diploid species are going to be same for single genetic locus then the species is said to be homozygous for that single genetic locus whereas if the both alleles of a given diploid species are different for single genetic locus then it is referred as \"heterozygosity\" for that locus. So that, if an individual is homozygous at one genetic locus on chromosome 12, is that not same individual homozygous at all loci on chromosome 12 because variance between the dominant and recessive traits. The species could be homozygous for dominant trait on the chromosome 12 or recessive trait with heterozygous nature
