The hormone calcitonin is controlled by a negative feedback mechanism because it's release leads to the decrease of calcium blood levels.
<h3>What is negative feedback mechanism?</h3>
A negative feedback mechanism is the defined as a type of regulatory mechanism in the body where by the increased output of a system leads to a decrease of another system.
Therefore, the release of the hormone calcitonin (increased level of calcitonin in the blood) will lead to decrease in blood levels of calcium.

Answer:
.45 from mom, .05 from dad
Explanation:
Given that:
the mother's genotype is AZ/az
i.e AZ = 50%
az = 50% (parental)
But we were also told that the recombination rate is 10% which will like wise affect the mother's genotype
So 100% -10% = 90 % of the mother's genotype
We have a new genotype
AZ = 45%
az = 45% (parental)
Therefore the probability of az gamete from the mother = 
= 0.45
Similarly; the genotype of the father is: Az/aZ
This is an heterozygous father who is diploid hence, there is a remarkable presence of two copies of each autosomal chromosome.
Az is the allele of the genes in one chromosomes and aZ is the allele of the genes in the other.
The gametes of this self cross are: Aa, AZ, az, zZ
Therefore; the recombinants are:
AZ
az
Since there are 10% recombinant; then
AZ = 5%
az = 5%
Therefore the probability of az gamete from the father = 
= .05
