Question

given below in a schematic diagram showing Mendel experiment on sweet pea plant having axel flower with round seed[AARR] and terminal flower with wrinkles seed[aarr] study the same and answer the question that follow (a) give the phenotype of F1 progeny​

Answer 1

Explanation:

(i) The phenotype of F

1

progeny will be Axial Round as it is dominant phenotype.

(ii) The phenotypes of F

2

progeny will be Axial Round, Axial Wrinkled, Terminal Round and Terminal Wrinkled as in F

2

generation, recessive trait is also expressed.

(iii) Phenotypic ratio of F

2

progeny will be 9:3:3:1.

(iv) Above observation are based on Law of Independent Assortment. This law states that factors or genes controlling different characters assort independently without influencing each other during the formation of gametes.
