UW Bio 180 - Exam 3 with Verified Questions and Answers species - ANSWER - evolutionarily independent population or group of populations synapomorphy - ANSWER - a trait that is found in certain groups of organisms and their common ancestor, but is missing in more distant ancestors; identifies monophyletic groups; homologous traits that can be identified at the genetic, developmental, or structural level biological species concept - ANSWER - reproductive isolation between populations (th...

Interpret this statement: Extinct fossil species are typically succeeded by similar living species - Answer Extinct and living forms represent ancestors and descendants Which is an example of developmental homology a) gene content b) similar organismal structures c)vestigial traits d) similar embryonic traits - Answer d) Which is not one of Darwin's 4 Postulates: a) Individuals in a population vary in their traits b) These differences are not heritable; they are not passed onto offs...

Bio 171 Exam 5 Quizzes, questions and answers, rated A+ As a population geneticist, you find a species of snails with more genetic diversity than humans. What does this mean? There is more variety in the gene pool of this snail species than the gene pool of humans. The allele frequency of all the alleles of one gene present in the population must add up to 1. (In other words, allele frequencies of all alleles for a given gene in a population must always add up to be 1, which is 100% of ...

BIO 405 Questions& Answers During speciation, what evolutionary forces might be responsible for divergence? - ANSWER: Genetic drift, natural selection(ecology), sexual selection Name and describe 3 species concepts that we might use to recognize species. - ANSWER: 1. Morphospecies concept (MSC)- based on morphological features, suitable for both living and fossil species, but it cannot identify cryptic species, which differ in traits other than morphology, and similarity might not indicate...

BIO1022 Week 1: Evolving Life: Natural Selection and the Tree of Life Note: This document outlines the major concepts for the week and is intended as a basis for structuring your study. The questions listed following this page are only intended to guide your understanding of the week’s content and not as example/practice questions. Answers will not be provided. Week 1 Learning Outcomes: 1. Explain the main requirements for natural selection to occur, and compare with artificial and sexu...

What is a synapomorphy? correct answers A trait that is similar in two or more species because it is derived from a trait that existed in a common ancestor. Why do synapomorphies arise during evolution? correct answers When a new species begins evolving independently, novel traits arise which are then passed on to its descendant species. What does it mean to say that one phylogenetic tree is more parsimonious than another? correct answers Fewer changes have to occur to make the origin of t...
