(5)Baldness is an X-recessive linked trait. Baldness is epistatic to curly hair which is dominant over straight hair. The gene which determines whether the hair is curly or straight is on an autosome. A bald male has a wife with straight hair and curly headed daughter. His daughter has children with a male with straight hair. The chance that one of their male offspring has a full head of curly hair is 1/2 for the purposes of this question, assume that if someone is bald, they will not have a full head of curly head even though in real life they might when they are younger. 6. When researchers studied hypertension (high blood pressure) in twins, they found a concordance rate of 36% for identical twins and 8% for fraternal twins. True or False: Since the concordance rate for identical twins is much less than 50%, genetics does not play a role in hypertension.

age 105 of 114 3 5 € BUD > D Q Autosomal Genes 1. Parental Cross: It is possible that your mutation is autosomal (dominant or recessive). In this case, you only need one Punnett square to make predictions for the F1 generation that will result from the parental cross, as it does not matter if the female or male in the parental generation is the true breeding mutant. a. Provide a Punnett square to predict the genotype of the F1 generation. b. Q Search If the mutant allele is dominant, predict the phenotype of the F1 generation. Make sure to also summarize the prediction as a ratio, comparing Wild-type : Mutant. c. If your mutant allele is recessive, predict the phenotype of the F1 generation. Make sure to also summarize the prediction as a ratio, comparing Wild-type : Mutant. 2. F1 Self-Cross: Take the F1 results from question #1 to create a Punnett square predicting the F2 generation genotypes. 104 a. What are the predicted F2 phenotypes if the mutant allele is dominant? Make sure to…

Tell me whether it is autosomal reccessive inheritance,autosomal domiant inheritance,sex-linked reccessive inheritance, sex-linked dominay inheritance or y-linked inheritance based on information given.(With Pedigree Anlaysis Breakdown)

Part III - Trait Analysis 1. The following pedigrees will be used to determine whether the trait is autosomal dominant or autosomal recessive. In tracing autosomal alleles, if both parents have the disorder and the offspring do not, the condition is autosomal dominant. If neither parent shows the disorder but some of their children do, the condition is autosomal recessive. A carrier is an individual who appears to be normal, but who is capable of passing on a gene for the disorder. If the characteristic is dominant, there can be no carriers because only a single gene is needed to show the disorder. Table II provides some keys for your answers.
