Question

279. In Antirrhinum two plants with pink flowers
were hybridzed. The F, plants produced red,
pink and white flowers in the proportion of 1
red, 2 pink and 1 white. What could be the
genotype of the two plants used for hybridiza-
tion? Red flower color is determined by RR,
and white by rr genes:
(a) RR
(b) Rr
(c)rr
(d)rrr

​

Answer 1

Answer:

rr thatts what i think it  is i dont care if im rong

Explanation:

Answer 2

Answer:

OPTION B

Explanation:

Here if we cross heterozygous ie, Rr with Rr then we get RR, Rr, Rr,rr. So now we get the phenotypic ratio:1:2:1,and genotypic ratio:1:2:1
