1 A heterozygous mutation is a mutation of only one allele. 2  A homozygous mutation is an identical mutation of both the paternal and maternal alleles. 3  Compound heterozygous mutations or a genetic compound comprises two different mutations in the paternal and maternal alleles.utations result from damage to DNA which is not repaired, errors in the process of replication, or from the insertion or deletion of segments of DNA by mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics (phenotype) of an organism.
Homozygous and Heterozygous. If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.Keep in mind that an organism can't simply be 'homozygous,' period.or example, the allele that gives rise to albinism is recessive, and the allele for normal pigment production is dominant. That means that a heterozygous individual with the genotype Aa, who has one copy of the normal allele and one copy of the albinism allele, would not be an albino.
