DD is homozygous dominant, the dominant allele will shown so they will have dimples.
What is homozygous?
When an organism is homozygous, it contains two copies of the same allele for a gene. When two copies of the same dominant allele or two copies of the same recessive allele are present in an organism, it is said to be homozygous dominant and homozygous recessive respectively. Homozygosity is the presence of two dominant alleles (AA) or two recessive alleles (aa).The recessive allele is suppressed by the dominant one.
What is heterozygous?
The two distinct alleles in a heterozygous genotype interact with one another. This controls how their characteristics are shown. This encounter frequently centers on dominance. The stronger allele is referred to as "dominant," whilst the weaker allele is referred to as "recessive." The dominant allele covers up this recessive one.
