- This lab exercise requires that we count certain Mendelian traits among students present in the lab. Your professor will explain each trait being addressed and will then ask students to identify if they are dominant or recessive for that specific trait. The collected traits will then be plugged into the Hardy-Weinberg Equilibrium formula in order to calculate frequency of Homozygous dominant, Heterozygous and Homozygous recessive individuals in the same. p2 + 2pq + q2 = 100 given data: trait: hair swirl 19 individuals total. 10 had the homozygous dominant hair swirl trait: clockwise the nine other were recessive please do a step by step explanation with the calculation using this data, as I am very unfamiliar with what values mean what and the equation itself thank you!Not all traits are controlled by dominant and recessive alleles. What does incomplete dominance mean? Give an example.If homozygous recessive (aa,tetrapter) f1 produces homozygous (aa) f2, what is the dominant and recessive trait of f2? Let’s say the dominant trait of the parents of f1 is Wild type and the recessive trait is Tetrapter.
- The allele for long whiskers in mice is dominant over the allele for a short whiskers. In a population of 500 individuals, 25% show the recessive phenotype. How many mice would you expect to be homozygous dominant and heterozygous for the trait?Sixteen percent (16%) of the population is homozygous recessive for a trait. What are the frequencies of the dominant and recessive alleles of that trait?In giraffes, long neck is dominant to short neck. Long neck is denoted by the dominant allele, N, while short neck is denoted by a recessive allele, n. Write the genotype and phenotype for the following organisms: homozygous dominant organism, homozygous recessive organism, and heterozygous organism.
- How would you distinguish a trait caused by a sex-linked recessive allele from one caused by a sex-influenced gene that is dominant? Why is coefficient of coincidence a basis for strength of linkage?Red hair in humans is inherited as a recessive trait. Bill and Sarah both have black hair. They marry and have four children, three of whom have red hair. Bill says it isn’t genetically possible for two black haired people to have 34 red-haired children, and he accuses Sarah of infidelity. Sarah says Bill is a homozygous dominant idiot and knows nothing about genetics. Who is correct and why?Suppose a geneticist is using a three-point test cross to map three linked rabbit morphology and behavioral mutations called si, It, and Le. The gene si is associated with the silky fur phenotype, and It is associated with the long-tailed phenotype. Both si and It are recessive mutations with respect to wild type. Le is a dominant mutation that confers the lethargic phenotype. The geneticist first crosses true-breeding lethargic rabbits to true-breeding silky fur, long-tailed rabbits. Next, the geneticist backcrosses the Fj progeny to the silky fur, long-tailed parents, and obtains the results reported in the table. Phenotype Number lethargic 815 silky fur, long-tailed 807 long-tailed 177 silky fur, lethargic 179 silky fur 7 long-tailed, lethargic 5 silky fur, long-tailed, lethargic 29 wild type 29 Place the genes in the correct order in the chromosome. Answer Bank si It Le

Dominant vs. Recessive genes 4. Codominance vs. Incomplete dominanceTay Sachs disease is a recessive lethal. Abnormally shortened fingers are the heterozygous form of a dominant lethal.
