Question

A homozygous plant having Axial (A) and Red (R) flowers is crossed with a

homozygous plant having terminal (a) and white (r) flowers.

(i) Give the phenotype and genotype of F1 generation. [1]

(ii) Mention the phenotypic ratio of F2 generation. [½]

(iii) Give the possible combination of gametes that can be obtained from F1

hybrid. [2]

(iv) Name and state the law that explains this cross. [1½]

(v) Why Mendel selected pea plant for his experiments? Give any two

reasons.​

Answer 1

1.The phenotype of the F1 generation will be axial red flower. Whereas the genotype of the generation will be e heterozygous dominant condition of both the alelle that is AaRr

Explanation:

• 2. The phenotypic ratio of the F2 generation will be 3: 1

• 3. the combination of the gamate that can be formed from the F1 hybrid are,

AR , aR ,rr , Ar

• 4.the mendel's law of dominant can explain the above characteristics. In case of heterozygous condition the dominant allele will take over. This results in the presence of the dominant character in the phenotype.

• 5. Mendel selected pea plant for his experiment because the life of the people and is very short. In addition to this it is able to produce pure hybrid after fertilization.
