Answer:
Multiple alleles can modify the classical Mendelian ratio by increasing the number of phenotypes.
For example, in a monohybrid cross, Mendel gets only 2 phenotypes however, in ABO blood groups (a classical example of multiple alleles) there are four phenotypes present in a population.
Lethal alleles are the alleles which when expressed result in the death of an organism. These alleles can be dominant, recessive or conditional (depends on interaction with another gene).
Thus, lethal allele reduces the ratio of the phenotype associated with it by affecting the survival of the organism.
For example, lethal yellow allele in mice results changes the phenotype ratio from 3:1 to 2:1

I want to say it is the middle layer. But not 100% sure. Sorry if its wrong.
The test result that would be elevated due to the fruity odor is ketones.
<h3 /><h3>What is urinalysis?</h3>
Urinalysis is a chemical, physical and microscopical examination carried out on a urine sample. This can be used to detect a wide range of disorders such as:
- urinary tract infections,
The dipstick method of urinalysis uses a stick that is made up of chemicals which are capable of detecting the following through a colour change:
- Ketones,
- sugar,
- proteins,
- acidity, and
- blood.
The presence of fruity odor in the urine sample signifies that there is excess ketone in the body due to ketoacidosis.
