Complete question:
Suppose "A" is a dominant gene for the ability to taste phenylthiocarbamide and "a" is a recessive gene for the inability to taste it. Which couples could possibly have both a child who tastes it and a child who does not?
a. father AA, mother aa
b. father Aa, mother AA
c. father Aa, mother Aa
d. father AA, mother AA
Answer:
c. father Aa, mother Aa
Explanation:
According to the given information, the ability to taste phenylthiocarbamide is a dominant trait and is imparted by the allele "A". This phenotype would be expressed in both homozygous and heterozygous conditions. The non-taster phenotype would be expressed in the homozygous recessive genotypes only.
To have both taster and non-taster children, both the parents should have at least one copy of the recessive allele. Among the given options, the father with genotype Aa and the mother with genotype Aa have the possibility to have both taster and non-taster children.
Aa x Aa= 3/4 taster (1/4 AA and 1/2 Aa): 1/4 non-taster (1/4 aa)
Timothy does not get a promotion at work because he has cancer is an example of genetic discrimination.
Explanation:
Genetic discrimination is termed so when an employer or an insurance company treats indifferently an individual with gene mutation or heritable diseases.
The act of not giving promotion and using the genetic information for the reason by the employer is indifferent and termed genetic discrimination as in case of cancer where life expectancy and large insurance claim is the reason.
Insurance companies do not give benefits or insurance to potential people having or prone for having the mutation and heredity disease.
To help overcome this discrimination federal level laws have been implemented as Genetic information non discrimination act. It strictly prohibits the indifferent behaviour of the employers and insurance companies.
