Strong Quote Int Paragraph Styles 4 Genetic Inheritance Patterns Retinitis pigmentosa (RP) can be autosomal recessive, autosomal dominant, or x-linked. Apparently the dominant forms are often less severe. Eric's form of RP is Usher's Syndrome, which is an autosomal recessive inheritance (i.e., you must get a copy of the defective carried on one of the chromosomes that determines sex. Usher's Type II is recessive, so for Eric this means that both his Mom and Dad are carriers of this condition.

A plant that is heterozygous for both traits is crossed with a plant that is homozygous recessive for both traits. What is the genotype and phenotype of the offspring? Saguaro cacti are very tall cylindrical plants that usually have two L-shaped arms, one on each side. Suppose you live in southern Arizona where the Saguaro cactus is common, and you happen to have one growing in your yard. Your Saguaro has two arms, but one is longer than the other. Now, assume that arm length in these cacti i controlled by a single gene with arms of the same length (A) being dominant to arms of different lengths (a). What is the genotype of your cactus? Could one of the parents of your cactus have had a phenotype with arms actusII. Write TRUE if the statement is correct and FALSE if otherwise. -7. A temale parent possessing an X-linked dominant mutation is considered a carrier and will not manifest clinical symptoms of the disorder. _8. Y-linked traits are passed from the father to son, without the occurrence of genetic recombination. 9. Somatic mosaicism results to abnormalities based on the amount and distribution of normal cells while gonadal mosaicism affects the germline tissues leading to a new dominant mutation. 10. A test cross is done to determine which allele is dominant and which is recessive.

Hemophilia is an x-linked disease in which the blood does not clot normally; it is sometimes called "bleeder's disease." Hemophilia is caused by a recessive allele (h). The dominant allele (H) produces blood that clots normally. What is genotype of a man who is a hemophiliac? What is the genotype of a man with normal blood clotting? What is the genotype of a woman with normal clotting blood if her father was a hemophiliac? If a man with normal clotting blood and a heterozygous woman have children together, what would you expect for the genotypes and phenotypes of the children? 13. A dominant x-linked allele (B) gives normal color vision but the recessive allele (b) causes red-green color blindness.
