Answer:
a) The genes present on separate chromosomes exhibit indepedent assortment.
b) The genotype of tall and purple flower parent= TTPp
The genotype of short and purple flower parent: ttPp
Explanation:
a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.
b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.  
The genotype of tall and purple flower parent= TTPp
The genotype of short and purple flower parent: ttPp
 
        
             
        
        
        
In the medical profession, understanding the body position, direction and planes creates a common ground for the professionals to communicate in their work. For instance, if a nurse write down a medical note concerning a patient, the doctor will know exactly the part of the body that the nurse is referring to in her notes. It also makes it easy for doctors and nurses to diagnose the parts of the body where their patients are having problems. Thus, knowledge of human anatomy provides uniformity and precision in structures identification.

C. To track the direction the outdoor sunflower heads were facing throughout the day.
Explanation:
The main aim of the experiment being conducted by Jane  is to track the direction the outdoor sunflower heads were facing throughout the day. 
The whole set up is designed to test the claim that sunflowers do follow the sun in the sky throughout the day. 
- From experiment, Jill should be able to track the changes in the orientation of flower head throughout the day. 
- This will rightfully support his claims .
