- In your own words, explain the following concepts and provide at least one example for each: Continuous Variation (Minimum of 2 complete sentences.)Explain why in human families, many traits (albinism, phenylketonuria, blue eyes ) skip a generation while traits such as polydactyly, free earlobes and A and B blood groups do not.Phenylketonuria (PKU) is an inherited disease caused by a recessive allele. Individuals with PKU have two recessive alleles and have very low levels of an enzyme that is needed to properly break down proteins. If a woman and her husband are both carriers and have three children, what is the probability of each of the following? Show your math. (Hint: You can represent your probabilities as fractions or decimals, but probabilities are always between 0 and 1) a. All three children are of normal phenotype. b. One or more of the three children have the disease. c.All three children have the disease.
- Why Geneticists Use a Variety of Symbols for Alleles ? What are those ?Mendelian Genetics and Non-Mendelian Genetics: Huntington’s disease, a neurodegenerative genetic disorder that typically becomes noticeable in middle age, is due to an autosomal dominant allele. Sickle cell anemia, on the other hand, is a genetic blood disorder due to a recessive allele. Jillian is a carrier of the allele for sickle cell anemia but has no sign of any neurodegenerative disorder in her family. She married Jacobwhose father died of Huntington’s disease. His mother, however, is not inflicted with that condition. Neither of his parents exhibit sickle cell anemia. 1. Give the genotypes of Jillian and Jacob. Assuming that they will have 4 children, what is the probability that: 2. all their children will be normal? 3. they will have a son with Huntington’s disease? 4. they will have a daughter inflicted with both conditionsIn pre-DNA fingerprint days, blood type was often used in paternity disputes to exclude possible fathers. If the man in question has type B blood, and the child has type A blood, and the mother has type AB blood, can the man be the father of the child? Group of answer choices Yes, but only if he is homozygous for the B allele No Yes, but only if he is heterozygous for the B allele Yes, but only if both of his parents were Type AB
- Why The Same Genotype Does Not Always Produce the Same Phenotype?Gene dosage is important for a number of genetic phenomenon. Name two and explain their relationship to the genotype and phenotype observed.Mendelian Genetics The presence of a dimple on the cheek is governed by a dominant gene. A couple had already 4 children with dimpled cheeks. What would be the probability of having the next child as another dimpled if both parents are heterozygous for this character? Show your solution using Punnett Square
- In your own words, explain the laws of segregation and independent assortment from a molecular perspective. Alternatively, create your own analogy to illustrate these laws.On an episode of the science fiction television program Doctor Who, the “Progenation Machine” can take a tissue sample from an individual, duplicate all their chromosomes many times, then assemble a new individual with a complete set of homologous pairs by randomly selecting two of each set of chromosomes. If this actually worked, and wasn’t just a fictional construct, what is the maximum number of genetically distinct individuals that could be produced in this way from a humanI have seen that this was answered as C, Why is the answer C, how is that not evidence of it being genetic? Shouldnt it be none of the above? Question: Of the following, which supports the idea that alcoholism has no genetic or a low genetic component? a) Some strains of mice select alcohol over water 75% of the time, whereas others shun alcohol. b) The concordance value is 55% for MZ twins and 28% for DZ twins. c) Biological sons of alcoholic men who have been adopted have a rate of alcoholism more like that of their adoptive fathers. d) There is a 20% to 25% risk of alcoholism in the sons of alcoholic men. e) None of these.
