Complete the following queatione BEFORE ATTEMPTING THE HW 1 BLACKBOARD ASSIGNMENT, In the following human pedigrees, the filled symbols represnent the affected individuals who suffer from the disease. Use A/a to represent alleles for autosomal traits and XIX/Ytorepresent alleles for X-linked traits. Use the uppercase letter to represent the dominant allele and the lowercase letterto represent the receasive allele. afected fomale Unafected female affected male Unaffected male Pedigree 1: A. What is the most likely mode of inheritance of this disease? Choose from: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive. B. State the genotypes of individuals #1-#3. C. What is the probability that individual #4 is a carrier of this disease if his mother is homozygous dominant and his father is heterozygous?

Pedigree 2: A. What is the most likely mode of inheritance of this disease? Choose from: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive.

1. What role does a patient's genetics have in their symptoms of muscular dystrophy? What causes various mutations to cause distinct symptoms? (two to three sentences) (Think about why various mutations in different genes cause different illnesses.)2. What can family history teach you about a patient's muscular dystrophy inheritance and, hence, genetic basis? (two to three sentences)3. The X-chromosome contains the mutation that causes Duchenne Muscular Dystrophy (DMD). Explains how this impacts DMD inheritance and why DMD patients are disproportionately male. (two to three sentences)
Fragile X syndrome why is interesting Fragile X syndrome What are the symptoms or characteristics of this disorder or trait? What is the prevalence of the trait or disorder? What are the main genetic factors? s the genetic cause of this disorder or trait known? What gene(s) have been proven to be involved? Or, if not known, what genes are thought to be involved? Is it caused by a single gene? polygenic? Multifactorial? Devote a few paragraphs to this This could be one of the longest parts of the paper, if you choose to focus on this. If multiple genes are thought to be involved, discuss the specific role of at least one of them in depth (if known). Is the gene you’re discussing thought to play a major or a minor role in the phenotype? What chromosome is it on? What protein does it code for, and how might the protein possibly contribute to the phenotype? If no genes have yet been identified, indicate this, and devote at least one paragraph to any current efforts to determine which…
Does the phenotype indicated by the red circles and squares in this pedigree show an inheritance pattern that is autosomal dominant, autosomal recessive, or X-linked?
ess in males. A male i1s either normal or has colorblindness. He cannot be a carrier. The allele for colorblindness is carried on the X chromosome and is recessive. A man, whose father was colorblind, has a colorblind daughter. a) Is this man colorblind? How do you know? b) Where did he get his gene for colorblindness? c) Must the fathers of all colorblind girls be colorblind? Why? 1. A man whose parents were normal with respect for color vision marries a woman of normal vision and similar pedigree. One of their daughters is colorblind. Give the genotypes of this daughter, her parents, and paternal grandparents. Is the girl's father colorblind? 2. 100% Give Feedba 10 >>
tion 8: below is the pedigree of inheritance of phenylketonuria (PKU).

Aav AaBbCc Normal No Spacing Heading 1 Paragraph Styles In man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to depend on separate dominant genes located on different chromosomes. Normal vision and normal bones are recessive traits. A man with cataracts and nomal bones, whose father had normal eyes, married a woman free from cataracts but with fragile bones. Her father had normal bones. 11. What is the genotype of the man with cataracts and nomal bones? What is the genotype of the woman with normal vision and fragile bones? What type of offspring might this couple expect? Genotypes Phenotypes What is the probability that their first child will, (a) be free from both abnormalities (b) have cataracts but not fragile bones (c) have fragile bones but not cataracts (d) have both cataracts and fragile bones? lili
