Ratio between number of stamens in nine male flowers and number of carpels in three female flowers in Euphorbia is
1 : 1
1 : 3
2 : 1
2 : 3
A.
1 : 1
One male flower is represented by a single stalked stamen. So, nine male flower will have nine stamens.
Number of carples in one female flower is 3. So, in three females flowers numbers of carples will be 3 3 = 9
Therefore,

Select the option for correct pairing of nitrogenous bases in dsDNA.
(Py)Adenine = (Pu)Cytosine :: (Pu)Guanine = (Pu)Thiamine
(Pu)Adenine Thiamine(Py) :: (Py)Cytosine = (Py)Guanine
(Py)Adenine (Pu)Thiamine :: (Py)Cytosine (Pu)Guanine
Adenine(Pu) = Thiamine(Py) :: Guanine(Pu) Cytosine(Py)

Study the following statements.
I. F1 -progeny is the first hybrid generation and progeny resembles either of the two
parents.
II. F2 progeny is a resultant hybrid generation of cross pollination among F1 progeny and progeny shows retain as such both drawf and tall plants.
III. F2 progeny is second hybrid generation, produced by selfing F1 hybrids and progeny contained both drawf and tall plants.
IV. The proportion of probability of plants that were drawf were 1/4th of the F2 plants while 3/4th of the F2 plants were tall.
The correct statements are
