What can be expected for the recessive trait of monohybrids from the f2 generation?

all dominant traits
all recessive traits
1/3 dominant traits
2/3 recessive traits
none of the above

None of above.

Explanation:

A monohybrid cross uses pure breeding parents to get the F1 hybrid. Self crossing of F1 hybrid gives F2 generation in the phenotypic ratio of 3 dominant :1  recessive. Hence, the expected proportion of recessive progeny in F2 of a monohybrid cross is 1/4 only.

answer; i believe the correct answer is (anemia);

the answer would be   10%
