In addition to providing the gene and protein accession information for all of the homologs of FGFR3 that I could find on Homologene, I attempted to find images of as many achondroplastic phenotypes as I could. Interestingly there are breeds of animals in which people have selectively bred for this mutation, and I have noted this under the images. Additionally, images of this mutant phenotype could only be found in the mammalian homologs, which could indicate that a mammal would probably the best model organism for any studies about the mutation and it's effects on bone development and visible phenotype.
A BLAST search on the DNA sequence was run on the NCBI website. All of the homologs mentioned above, except for C.elegans (unfortunately its homolog did not come up in the search) had BLAST E-values of 0.0. An E-value of 1 implies that the sequence came up in the search merely by chance, as the value decreases towards 0, the match is less and less likely to be due to chance. So, the search provided very useful alignments. Additionally, most of the sequences had high alignment scores, as can be seen below:
