Genotypes are the genetic composition of the organism. The alleles for the genotype are located at the genetic loci of the chromosome inherited from each parent.
<h3>What are alleles and genetic loci?</h3>
The alternate version of the genes that code for the hereditary trait and characteristic of the organism giving them the genotype and the phenotype is the alleles.
Genetic loci is the designated position found on the chromosome of the organism possessing the alleles coding for the genotype that can be purebred dominant and recessive, and heterozygous.
Therefore, alleles are physically present on the loci.

Answer:
Among Sponges and Cnidarians, the difference among given facts is in "Have a network of nerve cells".
Explanation:
Both Sponges and Cnidarians have pores, they reproduce by buddings, and they live in freshwater. The major difference in both organisms is that: cnidarians have very simple nervous system made of sensory nerves that are arranged in the form of neural network. On the other hand, sponges are simple multicellular organisms without any neural network at all. In fact, they are the only multicellular organisms (animals) without a nervous system.

Explanation:
<span>RNA polymerase starts the transcription of a gene into mRNA by binding to a specific DNA sequence region called a promoter. RNA polymerase moves past the promoter until it reaches the start sequence of the gene to be transcribed in a 5 to 3 direction.</span>
