Whether most traits are significantly influenced by the environment and by the alleles of other genes that are individual inherits like for example Marfan disease. Introduction : The environment has a role in the occurrence of various diseases which includes various factors like polluted water, air, metal toxicity, poor health and hygiene, and effect of ultra-violet and infra-red radiations on the human body. The diseases like cancer are also caused due to the effect of chemicals, radiations and due to infection caused by virus and bacteria.

A couple enters your genetic counseling clinic for some family planning advice. The woman’s father was color blind, but her own vision is normal. The man has no family history of color blindness. Neither the man nor woman have any known history of hemophilia, but their first child (a boy) has hemophilia. They ask you to calculate the chance that their nextchild will be affected by one or both conditions. You remember from your genetics training that these are both X-linked recessive conditions and that they are closely linked: in fact, their genetic loci are separated by only 10cM! During the interview with this couple, you draw the following pedigree to represent their information. Given what you know, determine for this couple what chance they have of each of the following (in the table).

dominant-therefore someone with AB genotype has AB phenotype. You can see both because they are codominant) i) What are the possible genotypes for someone with A blood type? ii) What about B blood type? iii) Let's assume that an person by the name of Dustin Beilber (this name sounds really familiar for some reason) is taken to trial in a paternity suit by a woman claiming that he is the father of her child. He claims he is not the father. At the trial, an expert witness reveals the blood types of all three: Dustin's blood type – B Mother's blood type – A Child's blood type – O Based on these data, is it possible that Dustin is the father of this child? (To put this in terms of the scientific method, you are trying to disprove the hypothesis that Dustin is the father). If you can't disprove this, it doesn't mean that he is the father, it simply means that you cannot reject the hypothesis). Explain your answer.

In individuals affected by cystic fibrosis, salt crystals may appear afterperspiration dries up. In addition, the disease causes respiratory disorderswhich can be both debilitating and lethal. It occurs in individuals homozygousfor the recessive gene. Two normal parents had a daughter with thesymptoms of this disease, and a normal son who marries a normal womanwith an afflicted A test (salt concentration in perspiration of heterozygotes ishigher than normal) disclosed that both are indeed carriers of the gene. If thefirst child born to the mating in (b) was defective, what is the probability thatthe 2nd child would also be defective?Express answer in fraction form
