I wanted to watch only first part but it was too lovely so I've watched this as well.
I wonder whether there is any evidence that the observed change from argenine to cystine is the actual cause of colour change, or whether it could just be an accidental marker for another change that happened in that line of descent, such as in the control region or even a change that altered epigenetics (I note that what mice are fed on can change their colour epigenetically.) Can you say that the whole gene sequence (whatever that is – how do you define your gene) is the same except for that one mutation? Interesting that the gene you chose has no introns – most animal genes have introns don't they?
You talk of 'dominant' and 'recessive' alleles, but surely these are outdated concepts – an allele is only dominant over some other alleles but may be recessive to yet others, and there are many examples of hemizygous phenotypes where a 'half dose' of a gene product produces it's own effect compared to the heterozygous form. Quantitative gene expression is surely a big factor. Great talks and very well presented.
Awesome lecture…One day I'll join your Lab Mam..😎😘
