polymorphism is found in which phylum

Polymorphisms need not have slight morphologic differences within species, rather they can have behavioral differences in capturing, killing, and eating prey (McLaughlin et al., 1999; Swanson et al., 2003). The resultant PCR products are subsequently digested with restriction enzymes to produce multiple terminal restriction fragments (T-RFs). The phylum Platyhelminthes (flatworms) contains an important group of bilaterian organisms responsible for many debilitating and chronic infectious diseases of human and animal populations inhabiting the planet today. Results. There is a tendency to shift from finely divided submersed leaves in the submersed habitat to more coalesced entire leaves when leaves of the same … Answer: (a) 10. Secondly, using both molecular (methylation specific amplification polymorphism, MSAP) and immunological (enzyme-linked immunoabsorbent … 'hollow' and ἔντερον, enteron, 'intestine', referring to the hollow body cavity common to these two phyla. Since q is linear in c, q is maximal for c = 0 or c=1/2. As far as Hydra is concerned, there are four basic types of nematocysts which serve various functions.
