Gregor Mendel is known for 

(1) Species concept

(2) Hybridisation experiments

(3) Discovery of chromosomes

(4) Experiments on maize plant

A cross between tall and dwarf plant was performed and 120 offspring were produced in which 90 plants were tall and 30 were dwarf. Find out the genotype of their parents. 

(1) Tt and TT

(2) Tt and Tt

(3) TT and tt

(4) tt and tt

Who was the first to use statistical analysis and mathematical logics for solving biological problems? 

(1) Francis crick

(2) Gregor Mendel

(3) Hugo de vries

(4) W. Bateson

If F2 dwarf plants were self-pollinated then the genotype of F3 & F4 plants is 

(1) TT and Tt

(2) tt and tt

(3) tt and Tt

(4) Tt and Tt

Trait expressed in F1 generation is 

(1) Parental

(2) Recessive

(3) Dominant

(4) Recombinant

Which of the following is a monohybrid? 

(1) TT

(2) tt

(3) Tt

(4) None

Genotypic and phenotypic ratios of monohybrid cross are

(1) 3:1 and 1:2:1

(2) 1:2:1 and 3:1

(3) 1:2:1 and 1:2:1

(4) 3:1 and 3:1

What is the means of segregation in Law of segregation? 

(1) Allelic separation

(2) Chromosomal separation

(3) Crossing over

(4) Linkage

Incomplete dominance is present in

(1) Snapdragon flower

(2) Dog flower

(3) Antirrhinum flower

(4) All of the above

A cross was performed between pea plants P1 (violet flower) and P2 (white flower). If obtained progeny showed ratio of 1 (violet) : 1 (white) , then determine the genotype of P1. 

(1) Homozygous recessive

(2) Heterozygous

(3) Homozygous dominant

(4) Can’t be determined
