4. Analyzing:A. Analyze the pedigree below and determine if the trait is inherited as autosomaldominant, autosomal recessive, X-linked dominant, X-linked recessive, or Y-linked.Remember, data from human families is limited, so you may be unable todetermine the inheritance with certainty. The key is that you justify your answerusing data from the pedigree.5627111481215913410B. Two family members (individual four and individual 12) decide to undergogenetic counseling and testing for the disease.• Genetic testing shows that individual 4 has only nonmutant allele(s)• Genetic testing also indicates that individual 12 has only mutant allele(s)Does this information change your assessment of the inheritance of the disease? Ifso, explain why; if not, explain why not.

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…

1. Incomplete dominance governs the pigment gene of a flower. A mating between heterozygotes yields the following phenotypic ratio: 10 yellow flowers, 35 pink flowers and white flowers. Which statement describes the situation? a. The flower pigment gene is defined by a pink and yellow allele. b. The heterozygotes were yellow. c. The heterozygotes were white. d. The flower pigment gene is defined by a red and a white allele. 2. Mendel's rules do not correctly predict patterns of inheritance for tightly linked genes or the inheritance of alleles that show incomplete dominance. Does this mean that his hypotheses are incorrect? A. Yes, because they are relevant to only a small number of organisms and traits. b. Yes, because not all data support his hypotheses. c. No, because he was not aware of meiosis or the chromosome theory of inheritance. d. No, it just means that his hypotheses are limited to certain conditions. 3. Discuss the inheritance of hemophilia
