The gastrovascular cavity differs from the alimentary canal in that only the gastrovascular cavity has only a single opening. Gatrovascular cavity is the actual organ of digestion and circulation in the animal phyla Cnidaria and the Platyhelminthes. Alimentary canal unlike the gastrovascular cavity has two openings, the mouth on one end and the anus on the other end. Food goes in the mouth, while waste comes out the anus.
The answer is recessive alleles. Generally, a recessive allele
is the form of a gene that codes for a non-functional protein. When an individual inherits
recessive allele for a gene from both parents, then they are more likely to
suffer a disorder that is attributed to lack of the respective functional protein. Often the heterozygous individual will
not bear the disorder even though they carry
the recessive allele. This is because the
dominant allele is able to mask the
recessive allele by producing a functional
protein.
