Klug 107 solutions For example, mutations in one gene, FBN1, cause Marfan syndrome in humans. If you guessed that this rare mutation would be a recessive trait, you'd be wrong. Like many other genes, the mutant FBN1 allele is dominant to the wild-type allele. Dominance and recessiveness have nothing to do with whether an allele is wild type or mutant, or beneficial or harmful. There isn't a single phenotype associated with the mutant FBN1 allele—individuals with Marfan syndrome are tall, have disproportionately long limbs and fingers, an abnormally shaped chest, and often have heart and vascular problems. Therefore, the gene associated with Marfan syndrome is pleiotropic.

Organizational Behavior: Managing People and Organizations13th EditionJean Phillips, Ricky W. Griffin, Stanley Gully 174 solutions How is phenylketonuria an example of the principle of heredity environment interaction?A classic example of a gene-environment interaction is phenylketonuria (PKU), a disease caused by a mutation in the gene encoding the enzyme phenylalanine hydroxylase and in which the resulting enzyme deficiency prevents the metabolism of the amino acid phenylalanine.
How is PKU inherited quizlet?PKU is inherited in families in an autosomal recessive pattern. Autosomal recessive inheritance means that a person has two copies of the gene that is altered. Usually, each parent of an individual who has PKU carries one copy of the altered gene.
What is a person's genetic heritage his or her actual genetic material?The set of genes that an offspring inherits from both parents, a combination of the genetic material of each, is called the organism's genotype. The genotype is contrasted to the phenotype, which is the organism's outward appearance and the developmental outcome of its genes.
Which of the following might influence the environment of identical twins and therefore complicate the interpretation of twin studies?Which of the following might influence the environment of identical twins and therefore complicate the interpretation of twin studies? Adults may stress the similarities of identical twins more than those of fraternal twins. Identical twins might see themselves as a "set" and play together more than fraternal twins do.
