Achondroplasia is a dominant trait that causes a characteristic form of dwarfism. In a survey of 50000 births, five infants with achondroplasia were identified. Two of the affected infants had affected parents, while three had normal parents.

Part A

Calculate the mutation rate for achondroplasia and express the rate as the number of mutant genes per given number of gametes.

Express your answer using two significant figures.

In mice, the ability to run normally is a dominant trait. Mice with this trait are called “running mice” (R). The recessive trait causes mice to run in circles only. Mice with this trait are called “waltzing mice” (r) Hair color is also inherited in mice.Black hair (B) is dominant over brown hair (b). A) Cross a heterozygous running mouse with a homozygous running mouse. i. What are the parentgenotypes? __________ x ____________ ii. Draw the punnett square iii. What...

Colorblindness is a sex linked trait in humans. Normal vision is a sex linked dominant trait. A man’s maternal grandmother had normal vision; his maternal grandfather was colorblind; his mother is colorblind; his father has normal vision. What are the genotypes of the two grandparents and parents mentioned? What type of vision does the man have himself? What type have his sisters? If he should marry a woman genotypically like one of his sisters (he is not marrying one of...

If an individual has a dominant phenotype for a trait and produces an offspring with a recessive phenotype, which of the following is true? 1. We can't determine the genotype of the dominant parent 2. The offspring must have at least one dominant allele 3. The dominant parent is heterozygous 4. The other parent must have the recessive phenotype

Hi, I in Human Genetics.discussing questions on the single gene trait dwarfism and how ir relates to dominand and recessive gene alleles. My question is: When discussing how dominant gene alleles and recessive gene alleles determine expression of single-gene traits, such as dwarfism, what are the current prognostic, diagnostic and treatment capabilities for dwarfism? Thank you!

Q1. What is the dominant form of benzoic acid at pH 2. Suggest the dominant form of caffeine at pH 2. Q2. This lab uses a C18-reverse phase column. What does the stationary phase consists of? Is it polar or nonpolar? Q3. Predict whether benzoic acid or caffeine will come out of the C18-reverse phase column first at pH 2. Q4. To prepare the calibration standard solutions, calculate how much of each stock solution of sodium benzoate and caffeine should...

Suppose colourblindness is an X-linked recessive trait, while Huntington's disease is an autosomal dominant trait. Assume both traits are rare. A colourblind man decides to have children with a women who is heterozygous for both genes. What is the probability that they will have a child that is colourblind and does not have Huntington's?

Question 1 The two alternatives for a trait are red and white and red is dominant. However, white is the most common trait. What is the genotype of a homozygous dominant individual? a) RR b) rr c) WW d) ww e) red Question 2 Where the two alternatives for a trait are broad and narrow, and broad is dominant, the phenotype of a homozygous dominant individual would be expressed as a) BB b) nn c) Bn d) NN e) broad...
