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

Aim/Purpose - To demonstrate the effect of environment on phenotype 2To formulate a hypothesis about the effect of environment on phenotype To design and conduct a controlled experiment to demonstrate the effect of one environmental factor on a plant phenotype.

Jordan Alyce Norris November 7‚ 2014 Biology 111-J3 Predicting Patterns of Inheritance Using Monohybrid and Dihybrid Crosses Introduction This experiment was on Mendelian Inheritance; which is the inheritance of biological features that are based on the rules proposed my Mendel. The purpose of this experiment was to show how to predict patterns of inheritance by using Punnett Squares to perform monohybrid and dihybrid crosses. Two crosses were performed. Cross one consisted of heterozygous alleles

the Monohybrid Cross Values: Answers: Chi-square value Degrees of freedom P-value Questions: A) If all of the yellow (albino) seedlings were removed from the population‚ would the next generation still have a chance of displaying the albino phenotype? Explain your answer. B) How did the expected ratio of green to albino seedlings compare to the observed ratio of green to albino seedlings? Use your results to help explain your answer. C) What is the probability (as a percent) of growing a green

possessed mutation #644. It is a mutation in wing morphology that reduces wing size. A controlled cross was conducted between these two true-breeding mutant flies. Their progeny (F1) being heterozygous for both mutations displayed only wild type phenotypes. These two mutations in Drosophila are both believed to follow an autosomal recessive pattern of inheritance. Figure 1. Images Drosophila melanogaster with mutations.

remarkable field study of threespine sticklebacks. These fish closely relate to ecology and evolution. The researchers original findings are different than that of Robinson’s field study. His hypothesis states that the threespine sticklebacks varied phenotypes are the handiwork of natural selection supporting the discrepancy in the population. Diet and the environmental conditions are the variables found in this study. The ecologists also used evidence and observation to quantify results by using information

this‚ it is important to first distinguish between a child’s genetic inheritance and the actual expression of those genes. A genotype refers to all of the genes that a person has inherited. The actual express of these traits is the person’s phenotype. The phenotype can include physical traits‚ such as height and color or the eyes‚ as well as behavioral traits such as shyness‚ highly emotional‚ abnormal traits (ex. Schizophrenia). Some basic examples of
