The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).
For example:
If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>
Answer:
Behavioral responses in organisms require communication between an organism and its environment (option C).
Explanation:
The behavior of an organism depends on the function of relationship with the environment that surrounds it, and the way to respond to the diverse stimuli that are in this environment.
Behavioral responses always occur as a result of the interaction between the physical environment and other living organisms. This interaction triggers a series of stimuli that are perceived by the senses and processed by each organism, developing an appropriate response to each of them.
