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
Option A. is correct.
Hope it helped!
Children who are assertive and good at regulating emotions are more likely to help,share and give comfort to others in distress. If a peer is in distress they will react by frowning,lip biting, comfort seeking,rise in heart rate, and a sharp increase in EEG brain-wave activity in the right cerebral hemisphere that contains negative emotions.
The four principles of natural selection are variation (organisms within a population have their own individual differences in their appearance, such as, markings and color), inheritance (traits passed down to the offspring), high rate of population growth (which leads to their local resources to be more of a challenge to find), and differential survival/ reproduction (organisms in the population with stronger traits are more likely to survive and reproduce, aka survival of the fittest). These four principles work together to respond to chance in the environment by making sure the strongest survive and over time that species will adapt to their environment because the organisms with the better suited traits will pass their traits to its offspring.
I hope that made sense, lol.
