Imagine this. A couple wants to have a child. However, they both have had Cystic Fibrosis (CF) in their families and so, they want to know if there is a probability of their child inheriting CF. In this couple, if Mom's genotype is AaDD for the Cystic Fibrosis related alleles (as indicated above) and Dad's genotype of Aadd, what would be the phenotypic and genotypic ratios of the children they could have? If any of the children inherit CF, what can you tell about the severity of the disease? Would it be very severe, moderately severe, or not severe? Be sure to draw a Punnett Square to show how you arrived at the answer. asap please

Cystic Fibrosis (CF) is an autosomal recessive condition. Therefore, heterozygous (Cc) carriers do not display symptoms. Two parents who are carriers plan to start a family and you are a genetic counselor helping to advise them about their chances of having children affected by CF. a) Suppose the couple has 4 children, each one year apart. What is the probability that all 4 children will inherit CF? b) What is the probability that any 3 of their 4 children will not inherit CF, but 1 will be affected? c) What is the probability that their first child will not inherit CF, but the younger 3 children will inherit CF?
Single gene Mendelian inheritance patterns: if you are told the phenotype of the parents and whether the trait is dominant or recessive etc, be able to predict the genotype of the children. If you are told the phenotype of the parent as well as the inheritance pattern, be able to predict the parent’s genotype. Be able to set up and use a Punnett square to solve problems and make predictions. Be able to explain the major steps in how information from our genes is used to make proteins. Or to show it in a labeled diagram. Be able to explain whatis transcription, translation. Where in the cell do these processes occur? In what order? What type of molecules are being made [DNA, RNA, protein]? What are their building blocks? What is a mutation? How can a mutation in DNA cause a change in a protein? (use the following terms to answer: codon, transcription, translation, mRNA). What is gene expression? Why is regulation of gene expression important for normal…

Consider the following scenario: A man without freckles (freckles are a dominant trait, determined by the dominant allele “F”) is a carrier of cystic fibrosis (recall that CF is a recessive trait, determined by the recessive allele "a"), mates with a woman whose genotype is heterozygous for freckles and is also a carrier of CF. Assume the two genes in question are in different chromosomes and, therefore, assort independently. Complete the following Punnett square to generate the offspring probabilities from this couple, by entering the genotypes of the parents, the gametes, and the offspring for the two traits described above.

Male-pattern baldness is an example of a sex-influenced trait. The baldness allele, which causes hair loss, is influenced by the hormones testosterone and dihydrotestosterone, but only when levels of the two hormones are high. In general, males have much higher levels of these hormones than females, so the baldness allele has a stronger effect in males than in females. (B-baldness; N-full or normal) hair) A normal man marries a normal woman. What can be the possible genotypes of the parents respectively? * a. BN x BN b. NN x BN c. NN x bb d. NN x BB e. BN x bb f. BB x BB
This exercise is designed to give you some practice with Punnett squares and Mendel's principals of inheritance. Melanin is a chemical pigment produced in our body that contributes greatly to our skin, eye, and hair pigmentation -it also relates to color of fur, feathers, and such in animals. In general, the more melanin that is produced, the darker the color. A few genes contribute to the type and amount of melanin that is produced. Most people produce melanin in their skin, because it helps protect against the damages caused by the sun. This is why people tan. There is, however, a particular set of recessive alleles that cause a person to produce little or no melanin, and we refer to this as albinism. An animal or person who has little or no melanin is referred to as albino, and this can manifest in hair, skin, and eyes. For humans, this can be a rather dangerous condition as albinos are far more susceptible to sun damage, particularly cancer. In this exercise, the alleles are as…
1. Construct a pedigree chart of the trait traced in the situation below.2. The pedigree chart must be constructed with the names and genotypes at the bottom of every individual in the chart.If it is autosomal: Always use the first letter of the dominant trait to represent the dominant allele. For example, if the dominant trait is red, so the allele R-red, while r-yellow. For example, if the person is homozygous dominant for curly hair, we write CC as his genotype. If sex-linked, do not forget to write the parents’ chromosomes (XX-female, XY-male), with their corresponding superscripts (dominant or recessive). The superscript must be based on the first letter of the disorder. For example, the mother is a carrier of hemophilia (which is x-linked recessive), so we write XHXh. If the father has hemophilia, we write XhY. Put the pedigree chart using code properly. The situation is given below: Trait: NeurofibromatosisThe dominant form is neurofibromatosis, caused by the production of…

Cystic fibrosis (CF) is an autosomal recessive trait (a). Assume that Emily (who has CF) decides to have children with a man who does not have CF and who is not a carrier of CF. What are their genotypes, and what is the probability that they will have a child who is a carrier for CF?
Classical hemophilia is a sex-linked disease caused by a recessive gene on the X chromosome. (Hemophilia refers to diseases that cause delays in blood clotting.) If a woman who is acarrierof classical hemophilia has children with a normal male, give the ratios of the possible offspring with respect to classical hemophilia. Be sure to state both the genotypes and the phenotypes of each offspring. For genotypes, use X for a normal X chromosome, Xh for an X chromosome with the hemophilia gene, and Y for a normal Y chromosome. For phenotypes, if the offspring is female, be sure to state if homozygous normal, a carrier, or has the disease. If the offspring is a male, be sure to state if normal or has the disease.
