How do genetics (genetic predisposition) and the environment work together to cause substance abuse in individuals? What is the

vampirchik [111]

Answer: The drug abuse is influenced by the environment and exerts influence on the gene expressions.

Explanation:

The genetic make up of the person is decides, which genes will be expressed and develop a trait in an individual. But this genetic expression can be influenced by the environmental factors like food, exposure to sunlight, and others. This study which relate environment with the genetic make up is called epigenetics. No person is drug addict by birth but the consumption of drug can influence the genetic make up and traits in a abuser. So here, the environment is influencing the genetic basis of a abuser.

Which of the following is an example of genetic discrimination?

Rudiy27

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.

In cattle, RR = red, Rr = roan, and rr = white. What are the predicted color phenotypes for the offspring from crosses between:

timofeeve [1]

Answer:

a) 100% roan

b) 50% red, 50% roan

c) 50% roan, 25% red, 25% white

Explanation:

a) A red bull has the phenotype RR, a white cow has the phenotype rr. Let's do a punnett square. In its gametes, the bull only has R alleles to pass on, and the cow only has r alleles to pass on:

Bull

R R

r Rr Rr

Cow

r Rr Rr

The offspring can only be Rr, so all of them will be roan. (100% roan).

b) A red bull has the phenotype RR, a roan cow has the phenotype Rr. Let's do a punnett square. In its gametes, the bull only has R alleles to pass on, and the cow has an R allele and an r allele to pass on:

Bull

R R

R RR RR

Cow

r Rr Rr

50% of the offspring will be RR, and 50% will be Rr. So half of the offspring will be red, and half will be roan.

c) A roan bull has the phenotype Rr, a roan cow has the phenotype Rr. Let's do a punnett square. In its gametes, the bull has an R allele and an r allele to pass on, and the cow also has an R allele and an r allele to pass on:

Bull

R r

R RR Rr

Cow

r Rr rr

25% of the offspring will be RR, 50% will be Rr, and 25% will be rr. So half of the offspring will be roan, a quarter will be red, (RR), and a quarter will be white (rr)
