... Figure 1 shows the structure of three completely sequenced /3-tubulin cDNA clones. Similarity in the nucleotide sequence among the three clones was high in their open reading frames. For example, similarities between pTUB22 and R2242, pTUB22 and R1623. and R1623 and R2242 are 86.2%, 82.4%, and 81.8% ...

The population starts with an evenly distribution of alleles, as there are equal amounts of each allele for each gene locus. For 10 fishes we need a total of 60 alleles, thus we put 15 chi ...
