If the phenotype associated with a given version of a gene is observed when an individual has only one copy, the allele is said to be autosomal dominant. The phenotype will be observed whether the individual has one copy of the allele (is heterozygous) or has two copies of the allele (is homozygous).f the phenotype associated with a given version of a gene is observed only when an individual has two copies, the allele is said to be autosomal recessive. The phenotype will be observed only when the individual is homozygous for the allele concerned.
Phenotype refers to a trait that can be observed, such as morphology or behavior. Video Explaining the Differences. This video compares genotype vs. phenotype and further explains how the changes in genotype of an individual can affect it's phenotype. Determination The genotype can be determined through genotyping â the use of a biological assay to find out what genes are on each allele.
