More Droughts, Shrinking Sea Ice, Higher Temperatures, Less Snowpack
The allele which has light color appears to be altering transcription and that is why the corresponding mRNA is absent in zebrafish which is homozygous. The protein we can say were absent because mRNA which is being required for protein synthesis it was not present.
If the allele had altered translation, mRNA which is functional would have been present but in the same case, the protein will still be absent.
The largest mammal in the world would be
a Blue Whale... Hope this helps! :)
Introduced species can harm our planet because in some regions of the world we are not prepared for their type of species, which can all in all cause damage.
