In snapdragons, red × white produce pink. What proportion of pink flowers are expected from the cross pink ?
Your cross grid should look like this because both parents have one white allele and one red allele.



-----|--R-----|---W

R---|--RR---|---RW

W--|--RW--|----WW





The Ratio is likely to be 1:1:2



The answer is B, 1/2 will be pink.
Reply:you mean the cross between two pinks then C is the answer. If you meant a red x white cross then B.
Reply:Crossing pink with pink?
