Question

a plant of f1 generation with genotype AABbCc. on selfing what is phenotypic ratio in f2 generation​

Answer 1

answer 3:1

explain

ABC AbC

ABC AABBCC AABbCC

AbC AABbCC AAbbCC

The genotype of the F

1

generation plants is AABbCC. The number of gametes involved in the given cross can be calculated by 2

n

where n= 1 ( n is the number of heterozygotes). Hence there will two gametes ABC and AbC. On selfing these plants the phenotype of the F

2

generation will be 3:1 as shown in the Punnett square. Thus the correct answer is option A.
