In our lab‚ we had three main objectives. First‚ we evaluated our data on monohybrid and dihybrid corn cross seed counts against Mendel ’s theoretical expectations of independent assortment and the segregation of alleles. Next‚ we used the Hardy-Weinberg Theorem to provide a theoretically expected value for allele frequencies for single human gene traits. Lastly‚ we dealt with Drosophila melanogaster and we examined red and white eye alleles to determine if this gene is sex-linked or autosomal

EXAM1 Q1. How many chromosomes are in a typical red blood cell taken from a normal person? Zero Q2. The degree to which a trait is expressed in individuals is the expressivity of the trait. Q3. In pedigrees‚ a male individual is symbolized as a square. Q4. The chromosomal structure that anchors the spindle fiber to the chromosome is centromere. Q5. The short arm of a submetacentric chromosome is symbolized as the p arm. Q6. Genetic diseases transmitted only by a mother to both sons and daughters

Unit 3 - Evolution Notes Evolution involves change over time....from a biology standpoint evolution looks at how organisms change over long periods of time over many generations and hundreds of thousands of years. Source of Genetic Change Mutations are the source of genetic change * Neutral mutations - do not seem to benefit or harm the organism * Harmful mutations - negatively affect the life of organisms * Beneficial mutations - positively affect the life of organisms Artificial

The simulation experiment is intended to investigate the shift in population allele frequencies in response to selective pressure. We do not grow live populations and test them in our class due to the fact that we don’t have enough time. Also the populations have to go through generations which cannot be conducted in a classroom as a result of not being enough room to reproduce‚ and the organisms would not be in their natural habitat leading to the cause they might not even try to reproduce.This

Chapter 22 Descent with Modification: Darwinian View of Life Overview: Darwin Introduces a Revolutionary Theory On November 24‚ 1859‚ Charles Darwin published On the Origin of Species by Means of Natural Selection. Darwin’s book drew a cohesive picture of life by connecting what had once seemed a bewildering array of unrelated facts. Darwin made two major points in The Origin of Species: I. Today’s organisms descended from ancestral species that were different from modern species. II. Natural

Materials and Methods Section What came first was a bitter experience. We were given strips of PTC paper‚ so we could see if we tasted them. After spitting mine out‚ I knew right away I was a taster. Luckily for others‚ they weren’t tasters‚ and they didn’t get the thrill of having a bitter flavor enhance their mouths. What came next was swabbing our mouths. In order for us to get the DNA that we wanted to break down‚ we used the easiest supply of free DNA- our saliva. It was this saliva that was
