C. genetic
Explanation:
It looks at the gene pool of specific species in an environment.
There was less of it, making it more possible for the species to be extinct.
I guess the point about increasing level of oxygen is most correct......
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
