Review terms (write definitions for these terms) Extant Extinct Genotype Phenotype Synapomorphy Background: There are three extant species of elephant: Elaphas maximus (Asian elephants)‚ Loxodonta africana (African elephants)‚ and Loxodonta cyclotis (African forest elephants). Their taxonomic hierarchy is as follows: Kingdom: Animalia Phylum: Chordata

Determine the genotype of the purple flower if purple (P) is dominant and white (p) is recessive. (20) Answer: P-generation: The purple flower must have the P-allele because purple is dominant.

How do we know we know what each individual gene does? One way to investigate the function of a gene is to just remove the gene and analyze what happens to the organism. Let’s say we have a gene of unknown function in the human genome‚ an unidentified gene. First‚ compare it to other genes to see what similar sequences they have‚ if they code some similar sequences they might code for similar functions. However‚ if the gene the unidentified gene codes for something different we have seen before this

Evidence for evolution includes: 1. The oldest to newest fossils clearly demonstrate without exception an overall progression of life forms from basic to more complex. If there was no evolution there would be no progression of species complexity over time. There are species that have existed relatively unchanged for millions of years referred to as living fossils. This is not evidence against evolution‚ only evidence that the traits of those particular species have been very successful for survival

Chapter 12 Genomes Study Guide By: Divya Prakriya Concept 12.1 : There are powerful methods for sequencing genomes and analyzing gene products. • The goal of sequencing genomes is to identify mutations in DNA and relate them to phenotypes (ie. Understanding genetics) • Human Genome Project- 13 year project‚ used chemically modified nucleotides • Next generation DNA sequencing- uses miniaturization techniques 1st developed for electronics industry‚ as well as principles of

diploid stage. In yeast‚ the haploid cells are n=16 and the diploid cells are 2n=32. S. cerevisiae has two haploid mating types MATɑ and MATa. When the haploids mate‚ the diploids formed are heterozygous at the mating locus. In this experiment‚ the genotypes of the two respective stains were172 MATa ade2 his3 leu2 trp1 ura3 can1 and 196 MATɑ ade2 his4 leu2 trp1 ura3 can1. Each strain has a mutation at the his locus which means that the yeast is unable to grow unless it is in

What percentage of the offspring will show phenotypes resulting from crossovers? If you did not know that genes A and B were linked‚ how would you interpret the results of this

11 Genetic and Environmental Influences on Human Development 11.1 Introduction We may often wonder about the reasons and forces which shape our personality and character. Each one of us has a specific kind of nature which takes that particuler form because of the effect of two major factors. The first is the genetic make-up which we inherit from our parents‚ and the second influence comes from the various experiences we have in our interaction with our surrounding environment. This includes
