Summary Introduction
Introduction: Genetic disorder are caused due to abnormalities in the genome of a person and these disorders are inheritable from the parents to the offspring. Genetic disorders can be autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, Y linked, and mitochondrial disorders. For understanding the inheritance of human genetic diseases “Pedigree analysis” is considered the most effective tool and it follows simple Mendelian pattern.

- Hemophilia is a disease caused by a gene found on the X chromosome. Therefore, it is a sex-linked disease which is caused by the recessive allele. Suppose, a man with hemophilia marries a woman who is homozygous dominant for the trait, what is the chance of having children who are hemophiliacs? (XH = normal; Xh= hemophiliac) * a. 0% b. 75% c. 100% d. 25%arrow_forwardIf two parents are heterozygous for a genetically inherited dominant trait, what is the probability that they will have a child together who has this trait in his or her phenotype? a. 25% b. 50% c. 75% d. 100%arrow_forwardPolydactyly is a congenital physical anomaly in in humans, dogs, cats; and having supernumerary fingers or toes.

Which combination of parents are LEAST likely to produce a child with cystic fibrosis? A. 2 parents with cystic fibrosis B. 2 parents without cystic fibrosis C. 1 parent without cystic fibrosis and 1 with cystic fibrosis D. 2 parents who do not know if they have cystic fibrosisarrow_forwardHemophilia is a disease caused by a gene found on the X chromosome. Therefore, it is referred to as a sex-linked disease. The recessive allele causes the disease. A man with hemophilia (xhy) marries a woman who is homozygous dominant (XHXH. A.

The disease is usually passed from a mother to all children C. Pure-breeding pumpkin plants grown on sandy soil have bigger seeds than plants of the same pure-breeding lineage grown on peaty soil. D. A cross between a true-breeding plant with serrated leaf edges and a true- breeding plant with smooth leaf edges produces an F1 generation with 88% plants with serrated leaves. E. A cross between two heterozygotes, DdFf, produces offspring in three phenotypic groups; Long wings in offspring with genotype D_F_, short wings in offspring with D_ff, and no wings in offspring with the genotypes ddF_ and ddff.
