Question

Sheree is referred to a genetic counselor because a cystic fibrosis (CF) test done as a routine part of her prenatal care indicated that she is a carrier of the most common mutant allele. Sheree is stunned, because no one in her family has the disease. She is 26 years old. The genetic counselor would most likely Multiple Choice o explain autosomal recessive inheritance and suggest that Sheree's husband be tested for CF. O explain autosomal dominant Inheritance and suggest that Sheree's husband be tested for CF. O explain autosomal recessive Inheritance and suggest that Sheree's parents be tested for CF O advise Sheree to have amniocentesis to check the fetus for the CF genotype.

Answer 1

ам Cystic fibropis is disorder prevent disease are present on on autofonal recessive type of in tchee which when the allele when in recessive condition can cause the The allele of this trait the auto come to The genetic counselor job is to find out any defect in the parent based parente and to find out any defect deffect of those the developing offspring in offspring in female body. the Sheree es carrier of cystic fibrosis that меам } of her parent is heterozygous of carrier for the disease because if she is carrier then received recessive allele from of their parent History of the one a she one option 2 the condition is en correct because it say! that counselor should explain autosomal dominent but the es autosomal recessive dis ease option 13 for cystic fibrosis carrier need parenta is incorrect because if she is tested then there i no to test parent for CF because if her normal then and Sheree is then testing of Sheree parents advised by coneinpelor because et help Sheree in counpo unseling are normal will not will not

should not ons wer that her husband be not cleary the genotype the because Option 1 should tested for cystic fibrosis because it define developing fetus even if the her husband is carrier cystic fibrosis exactly say the genotype of the developing fetus. because ?
