Best part of biology fr

i dont understand how the parents phenotype is AA for normal and aa for muscular when i thought that phenotype is the one with visible characteristics and is the dominant one, so how is the muscular one not AA i just dont get how to determine which ones have capital letters please help my bio test is tomorrow

Thank you 😊

how do we know that normal mouse is dominant ? like how will i be ure im taking the right one being as dominant?

@xlayy_000

Its dominant when the condition is unaffected or the condition is not related example; if there was a family who is infected by this kind of cystic fibrosis and someone like john hasnt infected by it ,he is homozygous dominant. But if someone like maddy is a carrier then she is homozygous recessive. Also if someone like alexandra was infected by this condition she is heterozygous

Excellent!

Saved my exam

can you do dominance and codominance, sex determination and sex linked diseases ?

this is awesome

I have a question, how come you only split the parents' alleles into two gametes and say it is by meiosis even though in meiosis you make 4 sex cells not only two? Except from that great video though.

Thanks!

YOUR VOICE IS AS FRESH AS A CUCUMBER

WAIT 1 QS: how do u know that normal is dominant - AA- and muscular is recessive -aa

Take the out of Africa theory out of the equation because it is documented that all skin color was in America. And there are American "genetic " relations to oceanic people and Australians. So when it comes to markers, is there a way to tell who passed down that marker, which way it came from? For example, lets say an American has the same marker as an African, how can one tell which way it came from? Was it an American who passed it down to an African via past migration or was it an African who passed it down to an American? Are those markers exact matches or is it just similar to each other and somebody just went on ahead and said this is an African marker or this an American marker and they are genetically ancestral related? Or they saying they are genetically related because of similarities or exact matches? If so, how can they tell who receive what from who?
