Can anyone help me with how to calculate the genotype in bio..

or calculating the genotype frequency??

@d!_†oX!©:
is that an IGCSE doubt???/??i have never seen anything like that in the syllabus or any past paper...

thepokerpro:
yup its igcse....

ill give a link to the question...

please help...

nits94:
which past paper is it from?? I mean the year..

@d!_†oX!©:
ohhh this ways....dude u scared me...u dont need any of those things that u asked..
just see that P is dominant and p is recessive
so the yellow can only appear is it is pp
now make a genetic cross for each of the options nd u'll see that for the C part
the results are PP,Pp,Pp,and pp
so only one on four is yellow...
nd as u can see that very rarely yellow sorns are found in the diagram so the answer dhould be C

tell me if u still dont get it
