A knowledge of the different cell processes helps one understand the working of a cell at the better level. The process of binary fission was understood based on which population growth of bacterium was studied and doubling time was calculated. The difference between mitosis, meiosis and binary fission was understood as well. The main difference between photosynthesis and cellular respiration was seen and their roles were studied individually. Thus, the assignment gave a thorough insight into the working of different kinds of cells. Virtual Lab: Genetics Purpose: The aim of the work is to understand the basics of genetics and understand Mendel’ s laws of inheritance. Lab Observations: The virtual lab of drosophila established the laws of genetics where flies were selected according to their phenotypic characters and mated to obtain F1 and F2 generations.
The Punnett square helped to understand the percentage of offsprings that could have a particular wing trait. Each result of the experiment complied with the ratios established by Mendel. In the first generation we obtained all Wild types thereby understanding that the wildl type gene was dominant over the recessive vestigial wing.
In the F2 generation we get a mix of wild-type and vestigial wing indicating that the F1 generation must have been heterozygous in character. Lab Answers: A Phenotype and Genotype of Dragons. You do not have to be able to access the Dragon website to answer these questions. Define genotype and phenotype. Genotype- The genotype refers to the genetic makeup of an individual. Phenotype- Phenotype of an individual refers to the phenotypic or the physical characteristics of any organism which sir determined by its genotype. What is an allele? Each cell has two copies of every gene and these two copies are known as the alleles for the same gene. Drosophila Lab.
Enter as a guest. Buy and then breed a mutant black bodied female with a wild type (i. e. standard) male. Describe and explain the characteristic of the first generation (F1) of flies. Is the vestigial wing characteristic dominant or recessive?
