Question

q9 mendel found out that in the f₂generation, the \lost\ form of the trait always reappeared in about ______ 5 marks
1/3
3/4
1/4
25%
c and d

Explanation:

Mendel's experiments showed that when two pure - breeding parents with different forms of a trait are crossed, in the F2 generation, the ratio of dominant to recessive traits follows a 3:1 ratio. So the recessive (lost in F1) trait appears in 1 out of 4 plants, which is 25% or $\frac{1}{4}$.

Answer:

E. c and d (since $\frac{1}{4}=25\%$)
