Excellent presentation Professor, by starting with the basic terms and key words...

[@WhyNot-si4pj]

I think the term " PSEUDOALLELES " stands for another term in human genetics called " LOCUS HETEROGENITY " .
But the example you mentioned about the Drosophila fly eye size ' inheritance has the " CUMULATIVE GENES " mode of inheritance .

i like the audio improvement !

Thanks! Yeah, I’ve been filming in a new spot, and it took awhile to get it right. 😊

Wait a second. when you rank eye size depending on the pseudoallele combination, i think there is a mistake, or i am misunderstanding. so we have two similar, but different, closely placed - but still different loci - genes which can have the following alleles; Gene 1 can have Wild type (+) or Star (S). Gene 2 can have Wild type (+) or asteroid (ast). when ranking size based on pseudoallele recombination, you wrote that +/+ is the largest, followed by S/+, followed by ast/ast? what? how can two different genes express the same allele? did you perhaps mean +/ast or ast/+. and if they refer to the same gene in different chromosomes displaying different three different versions of +, S, and ast, then it means the three are possible alleles of the same gene and not PSEUDOalleles. am i missing something in here?

[@RakimBCasan]

what are the reason why pseudoallelism possible occurring in organisms?

[@BiologyProfessor]

Gene duplication events can allow the copy to evolve a new function.

[@RakimBCasan]

@@BiologyProfessor is that the only reason why pseudoallelism occur in an organism?
