A dihybrid cross is across between two different lines (varieties, strains) that differ in two observed traits. In the nameDihybrid cross", the "di" indicates that there are two traits involved (in our example designated R and Su),the "hybrid" means that each trait has two different alleles (in our example R and r, or Su and su), and"cross" means that there are two individuals who are combining or "crossing" their genetic information. Inour example, a pure strain of corn producing purple-starchy kernels (RR SuSu) is crossed with a purestrain producing yellow-sweet (rr susu). The starchy seeds are smooth, the sweet seeds are wrinkled. Theresulting F1 ears all bear purple-starchy (smooth) kernels. Plants that are heterozygous for two traits arecalled dihybrids. When the F1 is self-pollinated, the resulting F2 generation contains various combinations(Figure 11.4).Figure 11.4: Dihybrid crossThe rules of meiosis, as they apply to the dihybrid, are codified in Mendel's first law and Mendel's secondlaw, which are also called the Law of Segregation and the Law of Independent Assortment, respectively(Table 11.1). For genes on separate chromosomes, each allele pair showed independent segregation. Ifthe first filial generation (F1 generation) produces four identical offspring, the second filial generation,which occurs by crossing the members of the first filial generation, shows a phenotypic (appearance) ratioof 9:3:3:1, where:• the 9 represents the proportion of individuals displaying both dominant traits• the first 3 represents the individuals displaying the first dominant trait and the second recessive trait• the second 3 represents those displaying the first recessive trait and second dominant trait• the 1 represents the homozygous, displaying both recessive traits.39°F Mostly cloudy M n#3- Google Xb Answered: 1.What are the possib X611 Mendelian Genetics | Laborate Xhybrnid-cross-experiment-2Figure 11.4: Dihybrid crossThe rules of meiosis, as they apply to the dihybrid, are codified in Mendel's first law and Mendel's secondlaw, which are also called the Law of Segregation and the Law of Independent Assortment, respectively(Table 11.1).

Although Laurlanthalasa, Princess of the Qualinesti elves, is known for riding into battle on a silver dragon, this is not her main form of transportation. She generally travels by way of griffon. Although the allele for a "crown" of feathers around the head is dominant, it is rarely found in the wild. This may be due to the fact that it makes the griffons stand out, thus making them less effective hunters and more visible to their natural enemies, evil chromatic dragons. This scarcity also makes them prized by elven royalty. Lauralanthalasa was given a breeding pair of bald griffons by an admirer who claims that they are both hybrids for the crowned gene. Create a Punnett Square to determine if Lauralanthalasa will have any chance using these two griffins to produce crowned offspring.

Complementation tests of distinct recessive mutants, 1 through 8, produce the data in the matrix below. A plus (+) indicates complementation, meaning the phenotype of the combined alleles is wild type, and a minus (-) indicates a failure to complement meaning that a mutant phenotype results. Assume that the missing mutant combinations would yield data consistent with the entries that are shown. How many complementation groups are formed by these eight mutants?

stion 6 of 18 Suppose that a geneticist discovers a new mutation in Drosophila melanogaster that causes the flies to shake and quiver. She calls this mutation quiver, qu, and determines that it is due to an autosomal recessive gene. She wants to determine whether the gene encoding quiver is linked to the recessive gene for vestigial wings, vg. She crosses a fly homozygous for quiver and vestigial traits with a fly homozygous for the wild-type traits, and then uses the resulting F, females in a testcross. She obtains the flies from this testcross. Phenotype Number of flies vg* qu+ 230 vg qu 224 vg qut vg* qu 97 99 Test the hypothesis that the genes quiver and vestigial assort independently by calculating the chi-squared, X², for this hypothesis. Provide the X2 to one decimal place. X2 = Does the X value support the hypothesis that the quiver and vestigial genes assort independently? Why or why not? the partial table of critical values for X2 calculations to test this hypothesis.

Calibri 12 - BIU A Section 4: Monohybrid test cross A monohybrid cross is a mating where alleles of just one gene are tracked in the offspring. A test cross is a mating in which two parents (P generation) are crossed to give F1 (first filial generation) offspring, and then two F1 parents are crossed to give F2 (second filial generation) offspring. By tracking offspring through two generations, a test cross can reveal patterns of inheritance for particular genes. 9. In a cross between a black and a white guinea pig, all members of the F1 generation are black. The F2 generation is made of % black and % white guinea pigs. Diagram this cross, and list the genotypes and phenotypes for each generation.

1 (b). Nowadays, newborn babies are required to be tested for phynylketonuria (PKU), an autosomal recessive genetic disorder. If untreated, individual homozygous for PKU suffer mental retardation. In a recent year, 4 PKU babies were detected out of 126,o00 tested. Assuming Hardy-Weinberg conditions, What is the percentage of heterozygous carriers? (Give your answer in whole number, no decimal places, and include the % symbol without a space).

In the D2S441 locus, Sophie's allele [10, 12] is maternal and her allele 10 is paternal from [Sam or Bill only, Sam or Harry only, Bill or Harry only, Sam Bill or Harry (either 3)]. 2. Sophie's allele 13 for D19S433 is [maternal, paternal] and her allele 14 could have come from [Sam and Bill only, Sam and Harry only, Bill and Harry only, Sam Bill or Harry (either 3)]. 3. In the FGA locus, Sophie's allele [21, 22] is maternal and her other allele could have come only from [Sam, Bill, Harry]. 4. Based on all STRs in the 3 panels we studied, it is clear that [Sam, Bill, Harry] is Sophie's father. He has one allele of Sophie's alleles for all STR loci 5. Would these results stand in court as proof paternity: [Yes or No] 6. This type of DNA profiling can also be used to determine maternity. Is there any doubt that Donna is Sophie's biological…
