Answer:
The difference between a recessive phenotype and a dominant genotype lies in whether the physical trait is expressed only when two copies of the recessive allele are present (recessive phenotype) or when at least one copy of the dominant allele is present (dominant genotype).
Explanation:
The difference between a recessive phenotype and a dominant genotype lies in how they manifest in an organism's physical traits and genetic makeup, respectively.
Recessive Phenotype:
A recessive phenotype refers to a physical trait or characteristic that is only expressed when an individual carries two copies of the recessive allele.
In a recessive phenotype, the trait is masked or not visible when a dominant allele is present.
Recessive phenotypes are typically expressed in organisms that are homozygous for the recessive allele (carrying two copies of the recessive allele).
Examples of recessive phenotypes include blue eye color in humans, white fur color in mice, and straight hairline in humans.
Dominant Genotype:
A dominant genotype refers to the genetic makeup of an individual that includes at least one dominant allele.
Dominant genotypes are expressed in the phenotype regardless of whether the individual carries one or two copies of the dominant allele.
Even if an individual is heterozygous (carrying one dominant allele and one recessive allele), the dominant phenotype will be expressed.
Examples of dominant genotypes include the presence of brown eyes in humans (where the dominant allele for brown eye color overrides the recessive allele for blue eye color) and the ability to roll the tongue in humans (where the dominant allele for tongue rolling overrides the recessive allele for non-tongue rolling).
