The purpose of this investigation is to explore how Punnett squares are used to predict the outcomes of monohybrid genetic crosses. Punnett squares are used by scientists to figure out the probability of an offspring having a specific genotype. Using these "tables", you can determine the probability of the offspring of a single trait (allele), or when crossing multiple traits from parents. The Punnett square is a visual representation of Mendelian inheritance. SCENARIO 1 Make a cross between the following flies: 1.

A wild-type fruit fly (heterozygous for gray body color andred eyes) is mated with a black fruit fly with purple eyes. Theoffspring are wild-type, 721; black purple, 751; gray purple, 49;black red, 45. What is the recombination frequency betweenthese genes for body color and eye color? Using informationfrom problem 3, what fruit flies (genotypes and phenotypes)would you mate to determine the order of the body color, wingsize, and eye color genes on the chromosome?

The distance between two molecular markers that are linked alongthe same chromosome can be determined by analyzing the outcomesof crosses. This can be done in humans by analyzing a family’spedigree. However, the accuracy of linkage mapping in humanpedigrees is fairly limited because the number of people in mostfamilies is relatively small. As an alternative, researchers cananalyze a population of sperm, produced from a single male, andcompute linkage distance in this manner. As an example, let’ssuppose a male is heterozygous for two polymorphic STSs. STS-1exists in two sizes: 234 bp and 198 bp. STS-2 also exists in twosizes: 423 bp and 322 bp. A sample of sperm was collected fromthis man, and individual sperm were placed into 40 separate tubes.In other words, there was one sperm in each tube. Believe it or not,PCR is sensitive enough to allow analysis of DNA in a single sperm!Into each of the 40 tubes were added the primers that amplify STS-1and STS-2, and then the samples were…
Explain why the percentage of recombinant offspring in a testcrossis a more accurate measure of map distance when two genes areclose together. When two genes are far apart, is the percentage ofrecombinant offspring an underestimate or overestimate of theactual map distance?
As it turned out, one of the tallest Potsdam Guards had an unquenchable attraction to short women. During his tenure as guard, he had numerous clandestine affairs. In each case, children resulted. Subsequently, some of the childrenwho had no way of knowing that they were relatedmarried and had children of their own. Assume that two pairs of genes determine height. The genotype of the 7-foot-tall Potsdam Guard was A9A9B9B9, and the genotype of all of his 5-foot clandestine lovers was AABB. An A9 or B9 allele in the offspring each adds 6 inches to the base height of 5 feet conferred by the AABB genotype. a. What were the genotypes and phenotypes of all the F1 children? b. Diagram the cross between the F1 offspring, and give all possible genotypes and phenotypes of the F2 progeny
In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?

In most two-factor crosses involving linked genes, we cannot tellif a double crossover between the two genes has occurred becausethe offspring will inherit the nonrecombinant pattern of alleles.How does the inability to detect double crossovers affect thecalculation of map distance? Is map distance underestimated oroverestimated because of our inability to detect double crossovers?Explain your answer.
The question should be whether you reject or do not reject the Fisher test null hypothesis using data for all three institutions, not for two. Test that Mode ofInheritance is Autosomal Recessive forexperiments at each of three researchinstitutions At two research instructions, the parental cross is a affected(disease) male with an unaffected (wild‐type) female. Thecross of a male and female in the F 1generation produces thefollowing counts in the F 2generation: Question to be answered: Computethe Fisher Combined P‐value test using the data fromthe two sites, and draw a conclusion (reject, do notreject) the null hypothesis for the Fisher test, namelythat the specified MOI at each site is correct. https://onlinelibrary.wiley.com/doi/10.1002/aff2.68(only abstract) https://bigislandnow.com/2022/10/23/native-predatory-fish-help-control-invasive-species-in-hawaiian-fishpond-on-o%CA%BBahu/#:~:text=Jacks%20and%20barracuda%20in%20He%CA%BBeia,on%20the%20invasive%20mullet%20species.
DABS Exit Submit Required information A single-factor cross is one in which the inheritance of only one character and Its associated genotypes are followed. Punnett squares are often used to predict the outcomes of simple genetic crosses. Based on Mendel's laws, the genotypes of the parents can be used to predict the genes in their gametes and the resulting progeny. A Punnett square enables you to predict the types of offspring the parents are expected to produce and in what proportions. Sickle cell anemia is a recessive trait in humans.
