hi
i had doubt in hereditary and evolution chapter class 10 CBSE India
So now I know that the phenotypic ratio of the pea ( with reference to dwarfness and tallness) is 3 : 1
which can be interpreted as : for every 4 pea plants obtained by a peapod, there are 3 tall plants and 1 dwarf plant
( this is how ratios work ) so the statement is agreed
But if you refer the image below,...
You will see pea seeds .On average the number of peas per pod = 54 / 6 = 9 ( 54 peas within 6 pods )
So, The average number of peas per pod is 9 peas per pod
Suppose when Mendel crossed one flower of a pea and got one pea pod out of it with 9 pea seeds ( average number of peas per pod as calculated above ) how did he even come to the conclusion of the phenotypic ratio of the pea plant which is 3 : 1 experimentally ; when the total number of seeds is not even a factor of 4 ( i.e. 3 + 1 ; from the phenotypic ratio )
experts please explain ...
