Question

Determine whether the  phenotypes will be in either a a 9:3:3:1 or 1:1:1:1 ratio.

  • Yellow/Starchy (smooth)
  • Yellow/Sweet (wrinkled)
  • Purple/Starchy (smooth)
  • Purple/Sweet (wrinkled)

Observe the red and yellow kernels (up to 100) and use this to see the ratio and determine the deviation (number of observed minus the number of expected). 

 

I am having trouble on how to exactly get this. Please help. What is confusing me is how to determine the deviation. 

Expert Solution
Step 1

Inheritance or heredity refers to the process by which the traits present in parents are passed on to their offsprings. It can be achieved by both asexual and sexual reproduction. In this regard, Gregor Mendel proposed several laws or principles in 1865-66 which are considered as bases of inheritance. However, there are several phenomena that contradict Mendelian laws such as epistasis in which gene interacts and produces a different phenotype than expected as per Mendelian principles
