The following are the types of nervous system and their functions.
1. Parasympathetic- functions as the relaxing response.
2. Sympathetic - functions as the flight and fight response.
3. Autonomic - it functions as the controller of automatic response.
4. Somatic- functions as controling voluntary response.
5. Peripheral- works as motor nerves and sensory which runs from and to central nervous system.
6. Central- works as the main interpretation and center of processing.
<span>The genetic term used to describe an observable trait is phenotype. More specifically phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.</span>
0:3:1
Explanation:
Tasters have the dominant allele for the itter taste of PTC, they can be homozygous TT and heterozygous Tt.
Non-tasters are supposed as autosomal recessive characters
they are homozygous recessive tt when expressed
Given in the equation two heterozygotes parents would produce offspring with the trait in the following ratio.
Tt (parent 1)
Tt (parent 2)
If a punnet square is made
T t
T TT Tt
t Tt tt
The phenotypic character is in the ratio of 0:3:1
There will be 25% chances of recessive trait of non-tasters in the progeny of heterozygous parents.
The first couple had two children: a healthy boy and girl.
5 people have the disorder(2 women and 3 men)
