Here we demonstrate how to induce and monitor regeneration in the Starlet Sea Anemone Nematostella vectensis, a model cnidarian anthozoan. We demonstrate how to amputate and categorize regeneration using a morphological staging system, and we use this system to reveal a requirement for autophagy in regenerating polyp structures.

Even though the human genome was mapped over 10 years ago, scientists are still far from understanding the function of every human gene! One way to evaluate how a gene functions is to disrupt the sequence encoding it and then evaluate the impact of this change (the phenotype) on the animal’s biology. This approach is commonly used in the mouse (Mus musculus), since it shares a high degree of genetic similarity with humans. To track the animals bearing genetic changes over several generations,...

SNP Genotyping

Single nucleotide polymorphisms, or SNPs, are the most common form of genetic variation in humans. These differences at individual bases in the DNA often do not directly affect gene expression, but in many cases can still be useful for locating disease-associated genes or for diagnosing patients. Numerous methodologies have been established to identify, or “genotype”, SNPs.JoVE’s introduction to SNP Genotyping begins by discussing what SNPs are and how they can be used to identify...
FAQs
Genotyping first targets selected genomic regions, then uses polymerase chain reaction to amplify those regions so they can be examined. Sequence differences or other molecular markers provide distinguishing patterns among individuals. Comparing these patterns allows researchers to assign genotypes consistently, creating a genetic framework for relating individual variation to developmental or biological traits.
A confirmed genetic background helps researchers determine whether an observed developmental or biological difference is associated with the factor under study rather than an unrecognized genetic difference between experimental animals. This strengthens gene-function studies and supports more reliable comparisons of embryonic patterning, regeneration, symbiosis, and other phenotypes.
Researchers can compare genotypes with traits observed during development or in later biological processes. When genetic differences correspond with variation in embryonic patterning, regeneration, symbiosis, or another phenotype, the data provide a basis for investigating genotype-phenotype relationships. Genotyping therefore helps organize developmental observations around specific inherited or molecular differences.
Genotyping individuals from different populations reveals patterns of genetic variation that can be compared with biological traits. These comparisons broaden developmental research beyond a single experimental background and help identify whether a phenotype is associated with genetic differences among populations. The resulting context supports studies of conserved developmental mechanisms across varied genetic backgrounds.
The workflow begins by isolating genomic DNA from each sea anemone individual. Researchers then amplify selected target regions with polymerase chain reaction and analyze sequence differences or molecular markers. The resulting molecular patterns are used to assign genotypes and can be matched with developmental observations, inheritance data, or other recorded phenotypes.
Genotyping supplies the genetic information needed to classify experimental animals and compare their associated traits. In gene-function studies, these assignments help relate genetic background to developmental outcomes. In inheritance analysis, genotype data provide a way to examine how genetic variants are distributed among individuals, supporting interpretation of trait transmission and biological variation.
