Q. What is the expected genotypic ratio in the F2 generation of a monohybrid cross?
A.1:2:1
B.3:1
C.9:3:3:1
D.1:1
Solution
The expected genotypic ratio in the F2 generation of a monohybrid cross is 1:2:1, representing the homozygous dominant, heterozygous, and homozygous recessive genotypes.
Q. What is the expected phenotypic ratio in the F2 generation of a monohybrid cross?
A.3:1
B.1:2:1
C.9:3:3:1
D.1:1
Solution
In a monohybrid cross, the expected phenotypic ratio in the F2 generation is 3:1, where three offspring display the dominant trait and one displays the recessive trait.
Q. Which of the following is NOT a characteristic of Mendelian inheritance?
A.Segregation of alleles
B.Independent assortment
C.Incomplete dominance
D.Dominance
Solution
Incomplete dominance is not a characteristic of Mendelian inheritance; it describes a situation where the phenotype is intermediate between the two parental traits.
