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…

E. D. A. B. 11. C. Huntington's disease is a degenerative disease of the nervous system that strikes in middle age. The allele that causes the disease (H) is dominant to the allele that results in the normal condition (h). Answer the following questions about the inheritance of this disease. What is the genotype of a man who is normal but whose father had Huntington's disease? What is the genotype of a woman who has Huntington's disease if both of her parents had Huntington's disease? If a man who is heterozygous for Huntington's disease marries a woman who is normal, what would you expect for the genotypes and phenotypes of their children? If a normal man marries a woman who is homozygous for Huntington's disease, what do you expect for the genotypes and phenotypes of their children? Since Huntington's disease is caused by a dominant allele, does this mean it's also the most common allele in the population? F. Since Huntington's disease is caused by a dominant allele, does this mean…

Based on an X-linked recessive pattern of inheritance, work out the likely genotypes of the individuals indicated by the letters. Individual A Individual B Individual C GENOTYPE ii. If individual C has children with a normal male, what are the chances that they will have haemophilia? Explain your answer fully. iii. If individual C has children with a normal male, what are the chances that their daughters will be carriers of the condition? Explain your answer fully.

Some traits are expressed by both in the male and female humans,but kindly elaborate such traits which are only present in male or in female, give example/s which could be explain under sex-limited and sex-influenced genes.
A. In man, hemophilia, the "bleeder's disease" in which the time required for blood to clot is greatly prolonged, requires the presence of the recessive allele of a sex-linked (found on the X chromosome). Remember to list the genotypes and phenotypes of the sons and daughters separately. gene

SUBJECT: GENETICS Topic: Probability 1. Consider albinism a trait to occur in a human family. If two parents areheterozygous for such trait, the probability of having a normally pigmented child is 3//4 and having an albino child is ¼. What is the probability that 2 will be normal and 1 will be albino?
.Certain forms of human color blindness are inherited as X-linkedrecessive traits. Hemizygous males are color-blind, but heterozygous females are not. However, heterozygous females sometimeshave partial color blindness.A. Discuss why heterozygous females may have partial color blindness.B. Doctors identified an unusual case in which a heterozygousfemale was color-blind in her right eye but had normal colorvision in her left eye. Explain how this might have occurred.

Cross a female who is a carrier of the gene for hemophilia with a man who has normal blood clotting. Tell the expected phenotypic ratio of the offspring. 3. Cross a female with normal color vision, but whose father was colorblind, with a man who has colorblindness. Tell the expected phenotypic ratio of the offspring. 4.
