Students will analyze and draw conclusions from their observations.Note: Prior knowledge and understanding of the following to successfully answer the simulation questions:- Gen, This digital lab, made on google slides, asks students to determine the inheritance pattern of a fruit fly trait by performing genetic crosses (using an online simulator.) Earlier, we said that female flies have an XX genotype and male flies have an XY genotype. FRuit Fly (Drosophila) Virtual Lab more extensive virtual lab through a program created by Virtual Courseware, requires set up by teacher. Are you getting the free resources, updates, and special offers we send out every week in our teacher newsletter? Save my name, email, and website in this browser for the next time I comment. It is typically used because it is an animal species that is easy to care for, has four pairs of chromosomes, breed quickly, and lays many eggs. Gregor Mendel created two main laws prior to his experiments with his growing pea plants. In mammals, the Y chromosome contains the gene SRY, which triggers testis development. The first law he created is the law of segregation. You will need to be able to tell the males 2. The answer to the question determines what color to use on the fruit fly at the bottom of the page. Includes an explanation of results and error analysis of lab performed. Wild type traits tend to be dominant to many of . Let's look at some of his data. joanna_zborowska7.

Half the gametes carry one allele, and the other half carry the other allele. Wild Type Female x Vestigial Winged Male, Wild Type 23 What is the fruit fly's diploid number? It states that the two members of a gene pair (alleles) segregate (separate) from each other in the formation of gametes. Probability (p) The members of a homologous pair separate in meiosis, so each sperm or egg receives just one member. Allowing for some deficiency in recessives, this was not unlike what Mendels theory predicted. You'll get a detailed solution from a subject matter expert that helps you learn core concepts.

Exercise 7 - Level 1, Fruit Fly This virtual lab goes through genetics where the students "mate" fruit flies to analyze the phenotypic ratios of the offspring. It offers a choice of three crosses for analysis: monohybrid, dihybrid, and sex-linked. 4. What were the key factors that influenced the outcomes?). Drosophila genome is 60% homologous to that of humans, less redundant, and about 75% of the genes responsible for human diseases have homologs in flies (Ugur et al., 2016). The first mutant white allele isolated (called w1) arose spontaneously because of transposon insertion. The other is the X chromosome.
