A. 1/4 pink
B. all pink
C. 1/2 pink
D. 3/4 pink
E. no pink
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?
Two possible answers: If we assume that the gene codes for both red and white (but that both produce pink) then it's
Answer A (traditional)
rw X rw
1/4 red (rr)
1/4 white (ww)
1/2 pink (rw)
Answer B
Be careful though, because in some cases involving color, subsequent generations do not revert.
