If F1 generation has all tall plants and ratio of F2 generation is 3 tall : 1 dwarf, it proves _______________.
If F1 generation has all tall plants and ratio of F2 generation is 3 tall : 1 dwarf, it proves _______________.
The correct option is B Law of segregation
A.Law of independent assortment - When a cross
is made between two individuals different from each other in two or more characters,
then the inheritance of one character is independent of the inheritance of
another character. It is called Law of independent assortment. Due to this
reason, in the dihybrid cross, recombinants are formed.
B.Law of
segregation - During gamete formation, the alleles for each gene segregate from
each other so that each gamete carries only one allele for each gene. It is called
Law of Segregation. Because of this reason, in the monohybrid cross, in the F2
generation, 3 tall and 1 dwarf plants are formed.
C.Law of Dominance
- Expression of a character or trait, in a pair of contrasting characters, in a
heterozygous organisms is called Law of dominance. Due to this reason, in F1
plant only one character is expressed.
D.Incomplete
dominance - Appearance of new
phenotypes in the progeny other than parental phenotypes is called Incomplete
dominance. It is a deviation to Mendel’s experiment.
So,
the correct option is ‘Law of segregation’.
