3. Cystic fibrosis is a recessive genetic disorder that causes too much mucus to build up in the lungs. What rules of genetics do you need to use to solve this problem? a. b. Normal lung functioning (R) is dominant while having cystic fibrosis (r) is recessive. Jessica has cystic fibrosis while Jon is a carrier (a heterozygote). Use a Punnett square to predict the probability that one of their children will have cystic fibrosis. C. Genotypic ratio: Phenotypic Ratio:...

Albinism is a genetic disorder caused by an autosomal recessive allele. The dominant allele results in the wildtype pigmentation. a) If an albino marries a homozygous person for the wildtype pigmentation allele, what would be the expected phenotype and genotype of their children? b) If an albino marries a person with wildtype pigmentation but that carries the albino allele, what would be the expected phenotypes and genotypes of their children? c) Two parents of wildtype pigmentation had an albino child....

3. Albinism is recessive to normal skin pigmentation. A man who is a carrier for albinism but has normal pigmentation marries an albino woman. What are the genotypic and phenotypic ratios of possible children? 4. Left-handedness is caused by a recessive allele. A left-handed woman whose father and mother are right-handed marries a right-handed man whose mother is left-handed, father is right-handed and sister is left-handed. a.

Lab Exercise 10 6) Fragile X disorder is a sex linked recessive disorder. Albinism is an autosomal recessive characterized by a lack of pigment in the skin, eyes and hair. HINT: THE GENES INO INVOLVED ARE ON TWO DIFFERENT CHROMOSOMES! Kyra is a carrier for Fragile X disorder and is unaffected by albinism. Kyra's mother has unpigmented skin, eyes and hair. Kyra marries Randy who has albinism, and does not ha Fragile X disorder. a. What is Kyra's genotype? b....
