Dominant' traits will actually disappear faster if they are disadvantageous.
Think about it: if everyone who has even a single copy of a particular allele is at a disadvantage (manifests the phenotype, in this case six fingers), then even single copies are selected against.
In the case of recessive traits, selection occurs only against homozygous carriers, who may be very rare if the allele itself is rare.
A concrete example would be something like Tay-Sachs disease. If the allele that causes this were dominant, every carrier would die before adulthood, and it would occur only as a very rare de novo mutation. But because it is recessive, it persists for now; heterozygous carriers have no disadvantage.
<span>Euglena is eukaryotic, because they have organelles and a nucleus. </span>
They both use <span>light to energize the creation of glucose also
</span> <span>Chlorophyll is a green pigment found in most plants, algae, and
cyanobacteria that as you probably know attracts light, chloroplasts
absorb light and turn it in to a freeform of energy << this is
called photosynthesis. </span>
<span>Alleles
Each human body is composed of genes, and these usually come in pairs that are slightly different from each other. The different versions of genes are called alleles. Alleles are responsible for determining physical or notable characteristics and traits a specific person has. </span>
