Persistent depressive disorder.

Persistent depressive disorder (PDD) is a serious and disabling disorder that shares many symptoms with other forms of clinical depression.
Is this a question? I’m pretty sure this is not one
Answer:
Yes.
Probability of such child = 1/2 or 50%
Explanation:
According to the question, below are the genotypes and phenotypes possibilities:
aa = normal vision & no headache
Aa = normal vision & no headache
AA = blindness & headache
Male Female
Aa aa
Possible genotypes of progeny: Aa Aa aa aa
So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.
Mathematical expression is as under:
2/4 = 1/2 that means 50% progeny.
The hawk, a carnivore (animal meat-eater), is predating on the rabbit, an herbivore (plant-eater). So the hawk can be seen as the predator and the rabbit as the prey.
But another type of relationship important in Ecology is consumers. So producers are the plants that feed a food web. That makes the rabbits the primary consumers (herbivores) of these plants. Then the hawks become the secondary consumers (carnivores) of the primary consumers, by eating the herbivores.
Hope that this makes sense!
