Question

In a monohybrid cross between tall pea plants (TT) and short pea plants (tt) a scientist obtained only tall pea plants (Tt) in the F 1 generation. However, on selfing the F1 generation pea plants, he obtained both tall and short plants in F2 generation. On the basis of above observations with other angiosperms also, can the scientist arrive at a law ? If yes, explain the law. If not, give justification for your answer.

Answer 1

Answer:

yes law of dominance or law of segregationor law of inheritance

The trait of tallness is dominant

according to it,the characteristics of an organism are determined by internal factors which occurs in Pairs

Answer 2

Explanation:

two laws can be arrived

in F¹ generation

the law of dominance

in the F¹ generation two types of genotype TT and tt

here the T trait is dominant on the t

and all the offspring will be of Tt and tall

hence here the law of dominance can be justified.

the law of seperation

in the F² generation only one type of genotype is available Tt

here when it interbreed then three types of genotype will be produced

TT, Tt ,tt

these will be a ration of 1:2:1

this is because of the law of segretion or seperation
