If `F_(1)` generation has all tall plants and ratio of `F_(2)` generation is 3 tall : 1 dwarf, it proves

A

Law of dominance

B

incomplete asortment

C

law of segregation

D

Linkage

Text Solution

Verified by Experts

The correct Answer is:
C
Factors of a character present in an individual do not get mixed up and both the traits are recovered as such in the `F_(2)` -generation (3:1), though one of these is not seen at the `F_(1)` stage.

Pure tall plant is crossed to dwarf plant. F_(1) generation consists of only tall plants while F_(2) generation has both tall and dwarf in ratio of 3:1. The phenomenon is due to

Pure-bred tall pea plants are first crossed with pure-bred dwarf pea plants. The pea plants obtained in F_(1) generation are then cross-bred to produce F_(2) generation of pea plants. (i) What do the plants of F_(1) generation look like ? (b) What is the ratio of all plants to dwarf plants in F_(2) generation ? (c) Which type of plants were missing in F_(1) generation but reappeared in F_(2) generation ?

F_(2) generation has genotypic and phenotypic ratio of 1:2:1. It is

On selfing a plant of F_(1) -generation with genotype "AaBbCC", the phenotypic ratio in F_(2) -generation will be

If a plant heterzoygous for tallness is selfed, the "F"_(2) generation has both tall and dwarf plants. This proves the principle of:

(a) If we cross pure - bred tall (dominant ) pea plants with pure - bred dwarf ( recessive ) pea plant we get pea plants of F_ 1 generation. If we now self- cross the pea plants of F_1 generation, then we obtain pea plants of F_ 2 generation. (i) What do the plants of F_1 generation look like ? (ii) What is the ratio of tall plants dwarf plants in F_2 generation ? (iii) State the type of plants not found in F_1 generation but appeared in F_2 generation, mentioning the reason for the same. (b) What are homologous structures ? Give an example. Is it necessary that homologous structures always have common ancestors ?
