The balls P and Q didnt attract each other which means they had the same charges. As P is Negative thus Q will also be negative. As for R it is attracted to ball Q. Ball Q being negative will only attract positive or a neutral ball. As the choices don't state any choice about it being neutral, positive will be the choice.

Can someone please help me with the topic of inheritance
biology.
How to ace this topic??
1:Using the F1 plants from the last question, self pollinate these pea plants (i.e. use the alleles of the F1 as the parents). Set out the cross and state the ratio of tall to dwarf plants.
