DNA is unzipped by helicase at the origin of replication. There are several origins of replications in eukaryotic DNA replication, while only one in prokaryotic replication.
A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.
<h3>Dominant and recessive alleles</h3>
In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.
An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.
In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.
