1)
The law of segregation was 1st discovered by
Reginald C. Punnett
Watson and Crick
Gregor Johann Mendel
Robert Koch
2)
He discovered his laws in the year of
1865
1856
1834
1870
3)
The dissimilar heterozygous (Tt) controlling one character is known as
Hybrid
Monohybrid
Dihybrid
Tetra hybrid
4)
Mendel studied his research works on
Tomato plants
Ground nut plants
Green pea plants
Hibiscus plants
5)
Based on the law of Segregation the one factor dominates the other and is known as
Recessive
Equivalent
Dominant
Suppressive
6)
According to the Law of Segregation the cross between the heterozygous (Tt) is known as
Hybrid cross
Monohybrid cross
Dihybrid cross
Tetra hybrid cross
7)
Punnett square is a graphical representation which helps to calculate the probability of
All of these
Traits occurring in monohybrid cross
Traits occurring in heterozygous Tt
Traits occurring in genetic cross
8)
The Punnett square was developed by
Anton van Leeuwenhoek
Louis Pasteur
Robert Koch
Reginald C. Punnett
9)
The genotype of F2 generation having 1/4th of TT and 1/2 of Tt and 1/4th of tt. So the genotypic ratio of F2 generation is
1:2:1
1:2:3
1:3:2
3:2:1
10)
The phenotype of F2 generation having 3/4th of tall and 1/4th of dwarf. So the phenotypic ratio of the F2 generation is
3:1
3:2
4:1
2:1
