O O c. A person who has a gene allele for a disorder with reduced penetrance (60%) that is transmittedin an autosomal dominant pattern and is usually expressed after age 30 has reached the age of 50 without any manifestations of the disorder. He now states that he wishes that he had decided to have children now that he knows he cannot pass the disorder on to any children he fathered. Is this man's thinking correct? Explain This person is not right because he can still pass the disorder to his offspring. Penetrance is the proportion of individuals carrying a particular variant (or allele) of a gene (the genotype) that also express an associated trait (the phenotype). The individual exhibits signs and symtoms of genetic disorder. He did not develop features of the disorder, the condition is said to have reduced (or incomplete) penetrance. He is a carrier of the allele for this disorder. As carrier he can give the genetic information to his child who could have a complete penetrance and…
2/7 - <. Hair texture is an incompletely dominant trait in humans. The three phenotypes are curly, wavy and straight. Straight only occurs when both parents have straight hair. Curly hair also tends to follow this pattern. Only two wavy haired parents produce all three phenotypes. Please explain this observation using punnett squares.

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
