Mr. Juan had a severe car accident during his childhood. According to a genetic counselor, his acquired characteristic such as being lame until the end of his life can be passed to his future offspring. Is the advice from the genetic counselor correct? O Yes. The sex chromosomes were affected aside from the car accident. O No. Acquired traits can be altered by sexual reproduction. O No. Somatic cells were only affected but not the genes of the sex chromosomes. O Yes. All acquired traits can be heritable from one generation to the next generation.

As a genetic counselor, you may face some ethical dilemmas.Imagine that a couple came to your office to discuss potential color blindness in their children.The man is not color blind, but his wife is. They already have one daughter that is color blindand want to know the probability of future children having the disorder. First, you will need toexplain to the couple the difference between sex chromosomes and autosomal chromosomes andthat color blindness is caused by a recessive mutation in a gene found on the X chromosome.Once they understand this, you can then explain to them the probability of other offspring havingthe disorder. What is the dilemma in this case and why might you need to suggest to the couplethat they see a marriage counselor
Imagine that you are a genetic counselor, and a couple planning to start a family comes to you for information.

If our DNA contains all the information about who we are, how can something that does not involve changing the gene sequence cause changes in phenotypes? Describe briefly how these changes happen.
Eye colors are passed down through generations, but sometimes genetic variations can lead to surprising results in eye colors (dark eye color, still rocks!?) Some examples are found below. Is there truth behind the following? Provide explanations for your answer. Two parents with blue eyes cannot have a brown-eyed child and vice-versa. Eyes with more than one color stems from parents with two different eye colors. People with violet eyes are mutants. People with red or pinkish eye color can have dark-eyed parents.

Cystic fibrosis is an autosomal disease that mainly affects the white population, and 1 in 20 whites are heterozygotes. Genetic testing can diagnose heterozygotes. Should a genetic screening program for cystic fibrosis be instituted? Should the federal government fund it? Should the program be voluntary or mandatory, and why?

.a. Mutations in gene “X” are responsible for breast cancer and can be inherited into the next progeny. In one such case, one affected male parent (a father) who had only one affected parent (can be either male or female) too came to a genetic counselor. Upon the testing recommended by the counselor, it has been found that that male parent’s child has a 50% risk of developing the cancer. Can you discuss the inheritance pattern of this disease for this male parent? In which Mendelian disorder, all the children of a mother (both of her alleles of a gene on X chromosome are pathogenic) could also be affected?
In the future, gene technology may make it possible for parents to produce children with athletic ability, artistic talent, or high IQ. Do you have any ethical concerns about these possibilities? If so, where and how would you draw the line?
