    purpose of this lab is to understand how each offspring inherits its genotype and how its phenotype reflects it. Sex chromosomes determine the sex of the offspring‚ and the autosomes consist of all the other chromosomes that determine phenotypic traits. Dominant traits are the genes that are expressed‚ while the recessive traits are masked by the dominant traits. We used Drosophila melanogaster (fruit fly)‚ mutating the female fruit fly with a scalloped gene to change the phenotype of its offspring

    The Relationship between the Genotype and Phenotype of Drosophila melanogaster Eye Pigment Mariam Rahmanyar 100486882 T.A: Zahra Mortaji BIOL 2020 Results: Our TLC plate showed all colours expressed by the pteridine pigments for the wild-type Drosophila as expected (Figure 1). The sample A mutant which was a bright-red eye mutant also expressed the same pigments as our wild-type. Compared to the wild type‚ sample A pigment spots were lower intensity in colour under the UV

    about what a genotype is‚ what a phenotype is and how they can interact. Did you know that the composition of living organisms can be defined by two distinct parts – Phenotype and Genotype? In 1908‚ Wilhelm Johannsen introduced the distinction between genotype and phenotype upon realizing that the hereditary and developmental pathways were causally separate (Stanford University‚ 2011). While Phenotype and Genotype are depicted uniquely separate‚ they can interact. DEFINE GENOTYPE The first part

    A person’s genotypes is their genes‚ which make up their DNA. Alleles are the types of genes‚ come in pairs in a gene‚ and are responsible for a person’s phenotypes(Wanjie 29). Phenotypes are the physical characteristics of a person. Alleles are either characterized as dominant or recessive. The dominant allele presides over the recessive allele‚ making the recessive allele "hidden". Because the recessive allele is covered‚ that person’s phenotype will only show the dominant allele

    Temperature and Equilibrium Virtual Lab Change is influenced by many different factors in many different situations. If you imagine the 400‚000 gallons of water in a stream at the top of a hill‚ you can picture that they will flow down the hill in order to reach equilibrium. But what if the temperature outside is -40 degrees Fahrenheit? How might this change the movement of the water molecules down the hill? This virtual lab will allow you to explore how temperature changes affect two linked
