If there are class B mutations in the flower development genes of Arabidopsis thaliana, then determine the structures present in
kotegsom [21]

Answer:

Whorl-1- petals

Whorl-2- petals (mutant)

Whorl-3- carpels (mutant)

Whorl-4- carpels

Explanation:

ABC model of flower explains the role of various genes in the formation of a flower from the shoot. Each gene forms a particular structure of a flower in the following manner:

1. A gene -sepals. (Whorl-1)

2. A + B- Petals (Whorl-2)

3. B+ C - stamens (Whorl-3)

4. C- carpels. (Whorl-4)

If a flower lacks the B gene, the effect will be observed in the phenotype in which B gene is involved that is in the formation of petals and stamens or whorl 2 and whorl 3.

The flower will produce

whorl-1- petals

Whorl-2- petals (mutant)

Whorl-3- carpels (mutant)

Whorl-4- carpels
