Once the larvae have grown into adults, freeze the tube again to immobilize them for a while. Students start by examining the genotypes and phenotypes of the flies in the simulation. When the flies have grown up freeze them to immobilize them for a little while. Using fruit flies that have previously mated may result in mixed offspring, which skews experiment results. Students will complete various crosses to determine patterns of inheritance and investigate genetic expression. Are you looking for a comprehensive unit on Mendelian genetics for your high school biology class? Explain what a mutation is and discuss two types of 55 However, when I click the tab for TPT is doesnt open. gene linkage). where did the first white eyed fly come from? In the end, it was confirmed through the work of geneticist Thomas Hunt Morgan and his students, who studied the genetics of fruit flies. Studying the genetic makeup, transcription and replication of the fruit fly can assist in better understanding these processes in other eukaryotic organisms, such as humans. The first law he created is the law of segregation. It states that the two members of a gene pair (alleles) segregate (separate) from each other in the formation of gametes. Massachusetts Institute of This doesnt harm them, it just freezes their wings for a little while. Upon crossing this male with wild-type female flies, I found that the offspring did not conform to the expectations of Mendelian inheritance. recessive phenotypes, andmodes of Drosophila melanogaster, more commonly referred to as the fruit fly, is a microorganism that is both easy to breed and very small in size. The genotypic notation for a mutant gene for white eye color on the X chromosome
Morgan also found mutations in other genes that were not inherited in a sex-specific pattern. if Mendelian characters are determined by genes located on the chromosomes and if the independent assortment of Mendelian traits reflects the independent assortment if chromosomes in meiosis, why does the number of characters that assort independently in a given kind of organism often greatly exceed the number of chromosome pairs the organism possess? Use 10 or so F 1 for P 2 in a separate vial. Fruit Fly Genetics: Free Response Question I dont understand , Posted 5 years ago. there is no statistical significance. biological supply company (Carolina,
Use a Chi-Squared test on the F2 generation data to analyze your Fruit flies are also helpful in studying mutation. The Y chromosome is passed only from father to son, so analysis of Y chromosome DNA may thus be used in genealogical research. - a statement about a population parameter, -The hypothesis that states there is a difference between two or more sets of data. Students learn the basic life cycle of the fruit fly, Drosophila melanogaster, and review three types of genetic crosses. Female x Sepia Eyed, Vestigial Winged Male. Fruit fly populations are inexhaustible, simple to breed and are not costly subjects. Directions: Answer all questions in essay form. Y is the sex-determining chromosome in many species, since it is the presence or absence of Y that determines male or female sex. Now, would the white-eye trait reappear, segregating in the F2 progeny as Mendel had predicted? Drosophila Fly Genetics Lab Report Biology 101 Lab 26. When these rare eggs were fertilized by sperm carrying either X or Y, the offspring were the XXY daughters with 2X chromosomes from the mother, and X0 sons inheriting an X from the father (those with XXX and Y0 combinations died). Further, it demonstrates that the phenotype of an organism is dependent upon its genotype and is also dependent on surrounding environmental conditions. Technology | Office of Digital Learning, Creative Commons Drosophila melanogaster. The cross between a male wild type fruit fly and a female white eyed fruit fly produced the following offspring. I dont have an answer key for this one, student data can vary. It offers a choice of three crosses for analysis: monohybrid, dihybrid, and sex-linked. with genotype Xw+Xw) female fruit fly? a paint brush into piles of flies that have the same characteristics. -smaller than females. 22 Concept 1: Reviewing Mendels Laws. Clearly, it was not impossible to be female and white-eyed. . If any of the F2 females carried the white-eye trait but did not show it, then it should be revealed by a test cross to the recessive parent. Brothersister matings among the F1 generation produced a second generation (F2) with some white-eyed flies, all of which were males. For example, you could have students cross a VG BL with a heterozygous wild-type fly and have them brainstorm reasons why the results do not follow the expected (Mendelian) ratio. The fruit fly lab is a staple of many high school and
F Once you find your worksheet, click on pop-out icon or print icon to worksheet to print or download. Bridges found rare flies with surprising inheritance patterns: daughters that inherited X-linked traits (like eye colour) only from their mother, and sons that inherited their X-linked traits from their father. These . Introduction: Genetics by definition is the study of heredity and the variation of inherited. Sex Linked Traits Worksheet Transtutors. Around the turn of the 20th century, the biology community started to make the first tentative connections between chromosomes, meiosis, and the inheritance of genes. [1] And the second, which is the law of independent assortment. Based on the inheritance pattern, Morgan concluded that the eye color gene must be located on the X chromosome.
