Question
Using the two equations, p + q = 1 and p2 + 2pq + q2 = 1, answer the following questions.
Maple Syrup Urine Disease (MSUD) is an autosomal recessive condition that causes intellectual and physical disabilities, difficulty feeding, and a sweet maple syrup odor to the urine. In Costa Rica, the incidence of MSUD is calculated as approximately 1 in 8,000 newborns. Calculate the allele frequencies for the normal and disease alleles.

- A worldwide survey of genetic variation in human populations reported the autosomal codominant MN blood group types in a sample of 1029 Chinese individuals from Hong Kong. The sample contained 342 people with blood type M, 500 with blood type MN, and 187 with blood type N. Part A The number of people expected in each blood-type category is: Enter the values expected for MM, MN and NN blood-type categories, respectively, separated by commas and using two decimal places (example 1.02, 2.30, 3.45).arrow_forwardBlood type is determined by multiple codominant alleles of the I gene, IA, IB, and i, where ii results in type O. The genotypes of a husband and wife are IAIB x IAi. Among the blood types of their children, how many different genotypes and phenotypes are possible? Group of answer choices 2 genotypes, 3 phenotypes 4 genotypes, 3 phenotypes 3 genotypes, 3 phenotypes 3 genotypes, 4 phenotypesarrow_forwardAssumptions: . If the parent expresses the trait, they are homozygous dominant If the child/children express the trait but the parents do not, the parents are heterozygous. Traits selected: Brown Hair/Eyes And Widows Peak Write the Letters you will be using n the Punnet square for each trait: _Ww Bb_and_ww Bb_ Father Genotype: WW Bb Mother Genotype: ww Bb Parent Gametes possible gametes: possible gametes: Do you have the phenotype of either of the traits in the cross? If you do, which one? Are there any other offspring with either trait? Which trait? Which phenotypic probability did you fall into? Which phenotypic probability did other offspring fall into?

- Which of the following is a genotypic frequency? O aa = = 24% O A= 54% O a = 46% O Brown hair = 33%arrow_forwardPlease explain why Huntington’s Disease is a dominant allele, but its occurrence is very low in the population.arrow_forwardConsider an animal with genotype F/f. The possible gametes produced by this individual may be ½ F and ½ f. Choose the correct answer below. The explanation for the possible gametes produced is Mendel’s first law, of equal segregation. The explanation for the possible gametes produced is Mendel’s second law, of independent assortment. The explanation for the possible gametes produced is BOTH Mendel’s first law, of equal segregation AND Mendel’s second law, of independent assortment. The explanation for the possible gametes produced is NEITHER Mendel’s first law, of equal segregation NOR Mendel’s second law, of independent assortment.arrow_forward
