Answer 2

Answer:

1. Type of phenotype=2
2. Type of genotype=3
3. No. of Zygote=16
4. Phenotypic ratio=3:1
5. Genotypic ratio=1:2:1

Explanation:

Self-pollination is a form of pollination in which pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). When AaBB is self pollinated ,Each of the two plants will make 4 gametes

• AB, aB, AB, aB.

Total 16 offsprings will be produced on self pollination(AaBB×AaBB)

• AABB-4
• AaBB-8
• aaBB-4

1)Type of phenotype=2

(ABAB and AaBB will show same phenotype.)

2)Type of genotype=3

3)No. of Zygote=16 (Total offsprings produced on self pollination)

4)Phenotypic ratio=3:1(AABB+AaBB:aaBB)

5)Genotypic ratio=1:2:1(ABAB:AaBB:aaBB)
